EGFR INHIBITORS CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority from U.S. Provisional Application No.63/327,631, filed April 5, 2022. The entire contents of the aforementioned application are incorporated herein by reference. BACKGROUND EGFR (Epidermal Growth Factor Receptor) is a member of the erbB receptor family, which includes transmembrane protein tyrosine kinase receptors. By binding to its ligand, such as epidermal growth factor (EGF), EGFR can form a homodimer on the cell membrane or form a heterodimer with other receptors in the family, such as erbB2, erbB3, or erbB4. The formation of these dimers can cause the phosphorylation of key tyrosine residues in EGFR cells, thereby activating a number of downstream signaling pathways in cells. These intracellular signaling pathways play an important role in cell proliferation, survival and anti-apoptosis. Disorders of EGFR signal transduction pathways, including increased expression of ligands and receptors, EGFR gene amplification and alterations such as mutations, deletions and the like, can promote malignant transformation of cells and play an important role in tumor cell proliferation, invasion, metastasis and angiogenesis. For example, alterations such as mutations and deletions in the EGFR gene are found in non-small lung cancer (NSCLC) tumors. The two most frequent EGFR alternations found in NSCLC tumors are short in- frame deletions in exon 19 (del19) and L858R, a single missense mutation in exon 21 (Cancer Discovery 20166(6) 601). These two alterations, referred to as sensitizing mutations, cause ligand- independent EGFR activation and are referred to as primary or activating mutations in EGFR mutant NSCLC (EGFR M+). Clinical experience shows an objective response rate (ORR) of approximately 60-85% in EGFR M+ NSCLC patients treated first line (1L) with EGFR tyrosine kinase inhibitors (TKIs) erlotinib, gefitinib, afatinib and osimertinib (Lancet Oncol.2010 Vol.11, 121; Lancet Oncol. 2016 Vol.17, 577; N. Engl. J. Med.2017 Nov 18 Doi:10.1056/NEJMoa1713137; Lancet Oncol.2011 Vol.12, 735), thus demonstrating that EGFR mutant NSCLC tumors depend on oncogenic EGFR activity for survival and proliferation and establishing del19 and L858R mutated EGFR as oncogenic drivers of disease and thus, validating drug targets and biomarkers for the treatment of NSCLC. Osimertinib is a covalent third (3 ^rd ) generation EGFR TKI that is now the approved standard of care (SOC) in first line (1L) for the treatment of NSCLC harboring del19 and L858R mutations. With a progression-free survival (PFS) of 18.9 mo (JC Soria et al - NEJM, 2018 Jan; 378(2):113- 125), it shows a transformative outcome for patients compared to first generation TKIs. However, after an average of 10-12 months of treatment, resistance has been observed in almost all NSCLC patients (Lancet Oncol.2010 Feb;11(2):121-8.; Lancet Oncol.2016 May;17(5):577-89; Lancet Oncol. 2011 Aug;12(8):735-42). Additional 3 ^rd generation TKIs are being used in front line (e.g. lazertinib) and relay on the same covalent mechanism of binding to EGFR. The most prominent on-target resistance mechanism is due to the secondary mutation in EGFR of C797X (where “X” can be an “S” or a “G” or an “N” or a “Y” or a “T” or a “D”), which occurs in 7 % to 22 % of patients progressing on 3rd generation EGFR inhibitors used in front line (Blakely, 2012; Kobayashi, 2005). This secondary C797S mutation reduces the affinity of the drug with the target, thereby producing drug resistance, and resulting in tumor recurrence or disease progression. The resulting “double mutant” tumors, that harbors the sensitizing mutations del19 or L858R and the resistance mutation C797X (e.g., C797S), are no longer sensitive to 2 ^nd and 3 ^rd generation TKIs. There is no approved drug to treat the double mutant patients.1 ^st generation TKIs (gefitinib and erlotinib) are active against C797X (e.g., C797S) but they are poorly tolerated due to activity associated with wild-type EGFR inhibition, and do not control brain disease due to their low abiltiy to cross the blood brain barrier (BBB). There is an unmet need for a selective therapeutic agent that treats the double mutant tumors, that is brain penetrant and treats the brain disease, and with reduced toxicologies (diarrhea, skin rash) associated with wild-type EGFR inhibition. SUMMARY The applicant has discovered novel compounds which are effective inhibitors of certain mutant forms of EGFR (see Synthetic Examples 1-454 and 458-500). In particular, it has been demonstrated that the compounds of the present disclosure effectively inhibit certain mutant forms of EGFR. Compounds of the disclosure (also referred to herein as the “disclosed compounds”) or pharmaceutically acceptable salts thereof effectively inhibit EGFR with one or more alterations, including L858R or exon 19 deletion mutation, and C797X (e.g., C797S) mutation (hereinafter “EGFR with LRCS mutations” or “double mutant EGFR”) (see Biological Example 1) and can be used treat various cancers, for example, lung cancer (see Biological Example 2).

Table 1

In one embodiment, the compounds of Examples 455-457 and 458A in Table 3, and pharmaceutically acceptable salts thereof, are excluded from the disclosure. In some embodiments, the present disclosure provides a compound according to structural formula (A), (B), (C), (I), (II-1), (II-1a), (II-2), (II-3), (II-3a), (II-3b), (II-3c), (II-4), (II-4a), (II-5), (II- 5a), (II-6), (II-7), (II-7a), (II-7b), (II-8), (II-8a), (II-9), (II-9a), (II-9b), (II-10), (II-11), (II-11a), (II- 11b), (II-12), (II-12a), (III), (III-1) or (III-2), or any one of the compounds of disclosed in the examples (including intermediates) and Table 1, or a pharmaceutically acceptable salt thereof, wherein one or more hydrogen is replaced with deuterium. The term “pharmaceutically-acceptable salt” refers to a pharmaceutical salt that is, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, and allergic response, and is commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al. describes pharmacologically acceptable salts in J. Pharm. Sci., 1977, 66, 1–19. Included in the present teachings are pharmaceutically acceptable salts of the compounds disclosed herein. Compounds having basic groups can form pharmaceutically acceptable salts with pharmaceutically acceptable acid(s). Suitable pharmaceutically acceptable acid addition salts of the compounds described herein include salts of inorganic acids (such as hydrochloric, hydrobromic, phosphoric, metaphosphoric, nitric, and sulfuric acids) and of organic acids (such as acetic, benzenesulfonic, benzoic, ethanesulfonic, methanesulfonic, and succinic acids). Compounds of the present teachings with acidic groups such as carboxylic acids can form pharmaceutically acceptable salts with pharmaceutically acceptable base(s). Suitable pharmaceutically acceptable basic salts include ammonium salts, alkali metal salts (such as sodium and potassium salts) and alkaline earth metal salts (such as magnesium and calcium salts). Compounds having one or more chiral centers can exist in various stereoisomeric forms, i.e., each chiral center can have an R or S configuration or can be a mixture of both. Stereoisomers are compounds that differ only in their spatial arrangement. Stereoisomers include all diastereomeric and enantiomeric forms of a compound. Enantiomers are stereoisomers that are mirror images of each other. Diastereomers are stereoisomers having two or more chiral centers that are not identical and are not mirror images of each other. When the stereochemical configuration at a chiral center in a compound having one or more chiral centers is depicted by its chemical name (e.g., where the configuration is indicated in the chemical name by “R” or “S”) or structure (e.g., the configuration is indicated by “wedge” bonds), the stereoisomeric purity of the named or depicted stereoisomers at least 60%, 70%, 80%, 90%, 99% or 99.9% by weight. The stereoisomeric purity in this case is determined by dividing the total weight in the mixture of the stereoisomers encompassed by the name or structure by the total weight in the mixture of all of the stereoisomers. When a disclosed compound having a chiral center is depicted by a structure without showing a configuration at that chiral center, the structure is meant to encompass the compound with the S configuration at that chiral center, the compound with the R configuration at that chiral center, or the compound with a mixture of the R and S configuration at that chiral center. When a disclosed compound having a chiral center is depicted by its chemical name without indicating a configuration at that chiral center with “S” or “R”, the name is meant to encompass the compound with the S configuration at that chiral center, the compound with the R configuration at that chiral center or the compound with a mixture of the R and S configuration at that chiral center. When two stereoisomers are depicted by their chemical names or structures, and the names or structures are connected by an “or”, one or the other of the two stereoisomers is intended, but not both. A racemic mixture means a mixture of 50% of one enantiomer and 50% of its corresponding enantiomer. The present teachings encompass all enantiomerically-pure, enantiomerically-enriched, diastereomerically pure, diastereomerically-enriched, and racemic mixtures, and diastereomeric mixtures of the compounds disclosed herein. Enantiomeric and diastereomeric mixtures can be resolved into their component enantiomers or stereoisomers by well-known methods, such as chiral-phase gas chromatography, chiral-phase high performance liquid chromatography, crystallizing the compound as a chiral salt complex, or crystallizing the compound in a chiral solvent. Enantiomers and diastereomers can also be obtained from diastereomerically- or enantiomerically-pure intermediates, reagents, and catalysts by well- known asymmetric synthetic methods. “First eluting compound” or “Peak 1” in the Experimental section refers to an intended reaction product compound obtained from a chromatography separation/purification that elutes earlier than a second intended reaction product compound from the same preceding reaction. The second intended product compound is referred to as “Second eluting compound” or “Peak 2”. In the compounds of the disclosure, any position specifically designated as “D” or “deuterium” is understood to have deuterium enrichment at 50, 80, 90, 95, 98 or 99%. “Deuterium enrichment” is a mole percent and is determined by dividing the number of compounds with deuterium at the indicated position by the total number of all of the compounds. When a position is designated as “H” or “hydrogen”, the position has hydrogen at its natural abundance. When a position is silent as to whether hydrogen or deuterium is present, the position has hydrogen at its natural abundance. One specific alternative embodiment is directed to a compound of the disclosure having deuterium enrichment of at least 5, 10, 25, 50, 80, 90, 95, 98 or 99% at one or more positions not specifically designated as “D” or “deuterium”. As used herein, many moieties (e.g., alkyl, alkoxy, cycloalkyl or heterocyclyl) are referred to as being either “substituted” or “optionally substituted”. When a moiety is modified by one of these terms, unless otherwise noted, it denotes that any portion of the moiety that is known to one skilled in the art as being available for substitution can be substituted, which includes one or more substituents. Where if more than one substituent is present, then each substituent may be independently selected. Such means for substitution are well-known in the art and/or taught by the instant disclosure. The optional substituents can be any substituents that are suitable to attach to the moiety. Compounds of the disclosure are selective EGFR inhibitors. As used herein, the term “selective EGFR inhibitor” means a compound which selectively inhibits certain mutant EGFR kinases over wild-type EGFR and the kinome. Said another way, a selective EGFR inhibitor has no or low activity against wild-type EGFR and the kinome. A selective EGFR inhibitor’s inhibitory activity against certain mutant EGFR kinases is more potent in terms of IC ₅₀ value (i.e., the IC ₅₀ value is subnanomolar) when compared with its inhibitory activity against wild-type EGFR and many other kinases. Potency can be measured using known biochemical assays. Some compounds of the disclosure have the advantage of good penetration of the brain. The ability of a particular compound to cross the BBB and penetrate the brain can be assessed using a variety of known methods or combinations of such methods. One in vitro method that is frequently used to predict a compound’s in vivo brain penetration is P-gp efflux ratio. P-glycoprotein (P-gp) is expressed at the blood-brain barrier (BBB) and restricts the penetration of its substrates into the central nervous system (CNS). Compounds that are found to be good P-gp substrates in vitro (i.e., have a high efflux ratio) are predicted to have poor in vivo brain penetration. In order to measure the P-gp efflux ratio, Madin-Darby canine kidney cells overexpressing P-gp (MDCK-MDR1 cells) the apparent apical to basolateral permeability (Papp[A-B]) and the apparent basolateral to apical permeability (Papp[B-A]) for compounds is determined. The P-gp efflux ratio is a measure of the ratio of Papp[B-A]/Papp[A-B]. In some embodiments, a compound of the disclosure has a P-gp efflux ratio of less than 2, less than 3, less than 4, less than 5. Some compounds of the disclosure have the advantage of good metabolic stability. One indicator of good metabolic stability is high microsomal stability. Hepatic metabolism is a predominant route of elimination for small molecule drugs. The clearance of compounds by hepatic metabolism can be assessed in vitro using human liver microsomes (HLMs) or human hepatocytes. Compounds are incubated with HLMs plus appropriate co-factors or human hepatocytes and compound depletion is measured to determine an in vitro intrinsic clearance (Clint). The Clint is scaled to total body clearance (CL), and a hepatic extraction ratio (ER) is determined by dividing CL to standard human hepatic blood flow. Compounds that have a low hepatic extraction ratio are considered to have good metabolic stability. In some embodiments, a compound of the disclosure has a calculated ER of <0.3, <0.4, <0.5, <0.6. Pharmaceutical Compositions Pharmaceutical compositions of the disclosure (also referred to herein as the “disclosed pharmaceutical compositions”) comprise one or more pharmaceutically acceptable carrier(s) or diluent(s) and a compound of the disclosure (e.g., a compound of Formula (A) or (I)), or a pharmaceutically acceptable salt thereof. “Pharmaceutically acceptable carrier” and “pharmaceutically acceptable diluent” refer to a substance that aids the formulation and/or administration of an active agent to and/or absorption by a subject and can be included in the pharmaceutical compositions of the disclosure without causing a significant adverse toxicological effect on the subject. Non-limiting examples of pharmaceutically acceptable carriers and/or diluents include water, NaCl, normal saline solutions, lactated Ringer’s, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer’s solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, hydroxymethycellulose, fatty acid esters, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with or interfere with the activity of the compounds provided herein. One of ordinary skill in the art will recognize that other pharmaceutical excipients are suitable for use with disclosed compounds or pharmaceutically acceptable salts thereof. The pharmaceutical compositions of the disclosure optionally include one or more pharmaceutically acceptable carriers and/or diluents therefor, such as lactose, starch, cellulose and dextrose. Other excipients, such as flavoring agents, sweeteners, and preservatives, such as methyl, ethyl, propyl and butyl parabens, can also be included. More complete listings of suitable excipients can be found in the Handbook of Pharmaceutical Excipients (5 ^th Ed., Pharmaceutical Press (2005)). A person skilled in the art would know how to prepare formulations suitable for various types of administration routes. Conventional procedures and ingredients for the selection and preparation of suitable formulations are described, for example, in Remington's Pharmaceutical Sciences (2003 - 20th edition) and in The United States Pharmacopeia: The National Formulary (USP 24 NF19) published in 1999. The carriers, diluents and/or excipients are “acceptable” in the sense of being compatible with the other ingredients of the pharmaceutical composition and not deleterious to the recipient thereof.

The samples are processed, the nucleic acids are isolated using techniques known in the art, then the nucleic acids are sequenced using methods known in the art. Sequences are then mapped to individual exons, and measures of transcriptional expression (such as RPKM, or reads per kilobase per million reads mapped), are quantified. Raw sequences and exon array data are available from sources such as TCGA, ICGC, and the NCBI Gene Expression Omnibus (GEO). For a given sample, individual exon coordinates are annotated with gene identifier information, and exons belonging to kinase domains are flagged. The exon levels are then z-score normalized across all tumors samples.

Reactions proceeded until between 10% to 20% total peptides were phosphorylated at room temperature (25 ºC) and were terminated with 35 mM 2,2',2'',2'''-(ethane-1,2-diyldinitrilo)tetraacetic acid (EDTA). Product was detected using the Caliper mobility shift detection method where the phosphorylated peptide (product) and substrate were electrophoretically separated and measured. Percent activity was plotted against log concentration of compound and points to generate an apparent IC ₅₀ . The following enzyme forms of EGFR were examples that were used in these assays: EGFR WT (SignalChem, E10-112G) EGFR L858R (SignalChem, E10-122BG) EGFR (d746-750) (SignalChem, E10-122JG) EGFR L858R C797S (SignalChem, E10-122ZG) EGFR (d746-750) C797S (SignalChem, E10-122TG) Biological Example 2. Cellular EGFR Inhibition assays PC-9/A431 pEGFR AlphaLISA assays Inhibitory effects of compounds were evaluated in cellular assays that measure level of intracellular phosphorylation of EGFR in PC-9 (ECACC, #90071810, Milipore/Sigma) and A431 cell lines (ATCC, CRL-1555) using AlphaLISA sureFire ultra p-EGFR (Tyr1068) assay kit (PerkinElmer, ALSU-PEGFR-A50K). PC-9 cells were seeded at 3.125x10^5 cells/ml in 40µL phenol-free DMEM supplemented with 10% FBS per well of a 384 well plate (Corning, 3764), while A431 were seeded at 3.125x10^5 cells/ml in 40µL in phenol-free DMEM with 0.5% FBS. Cells were allowed to adhere overnight at 37 ^o C/5% CO ₂ . On the next day, compounds were transferred at 4-fold, 10-point serial dilution from compound source plate to cell plates using liquid handler Echo550 and were incubated at 37 ^o C/5% CO ₂ for 4 hours. A431 cells were stimulated prior harvesting for 10 min with EGF at final concentration of 30 ng/ml in the incubator. Medium was removed from the plates and cells were lysed with 10µL of 1x AlphaLISA lysis buffer (supplemented with 1x protease/phosphatase inhibitor cocktail) followed by shaking at 600rpm for 30 minutes at room temperature. Lysates were transferred to Optiplate (Apricot designs) and 5 ul of 1x acceptor bead mix (prepared just before use) was added to each well followed by incubation at room temperature for 1.5-2 h in dark. Then 5µL of freshly- made donor bead mix is added to each well under subdued lighting or green filters, was mixed well on the shaker and the plate was sealed and left for an overnight incubation at room temperature in dark. On the next day, the plate was read the Envision using standard AlphaLisa settings. Percent of pEGFR inhibition was plotted against log concentration of compounds to generate IC ₅₀ values. Biological assay data of the test compounds are provided in Table 2 below. For inhibitory activity against EGFR L858R C797S and EGFR (d746-750) C797S mutants, and for inhibition of phosphorylation of mutant EGFR in cells the following designations are used: ≤ 10 nM = A; 10.1-50 nM = B; and > 50.1 nm = C. Table 2

Additional Examples 455-457 and 458A were also prepared and tested, and were found to have inhibitory activities of greater than 10 μM in all three of the EGFR L858R, EGFR (d746-750) and EGFR PC9 biological assays described above in Biological Examples 1 and 2, see Table 3 below. Table 3
