DIAZEPANONE-FUSED PYRIMIDINE COMPOUNDS, COMPOSITIONS AND MEDICINAL APPLICATIONS THEREOF CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Application No.63/168,896, filed March 31, 2021. The entire contents of the aforementioned application are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] Lung cancer accounts for the greatest number of cancer deaths, and approximately 85% of lung cancer cases are non-small cell lung cancer (NSCLC). The development of targeted therapies for lung cancer has primarily focused on tumors displaying specific oncogenic drivers, namely mutations in epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK). Three generations of tyrosine kinase inhibitors (TKIs) have been developed for cancers with the most frequently observed EGFR mutations, however, other oncogenic drivers in the EGFR family of receptor tyrosine kinases have received less research and development focus and several oncogenic drivers, including insertions in the exon 20 gene of EGFR, have no currently approved therapeutics to treat their cancers. [0003] The mutation, amplification and/or overexpression of human epidermal growth factor receptor 2 (HER2), another member of the human epidermal growth factor receptor family of receptor tyrosine kinases, has been implicated in the oncogenesis of several cancers, including lung, breast, ovarian, and gastric cancers. Although targeted therapies such as trastuzumab and lapatinib have shown clinical efficacy especially in breast tumors, their utility in lung cancer has been limited. It is likely that this variation is due to tissue-specific factors, including the low potency of kinase inhibitors like lapatinib for the mutagenic alterations in HER2 that are observed in the lung cancer patient population, including insertions in the exon 20 gene of HER2. [0004] Given that many patients with mutations in EGFR and HER2 do not derive clinical benefit from currently available therapies against these targets, there remains a significant unmet need for the development of novel therapies for the treatment of cancers associated with EGFR and HER2 mutations.

The reaction mixture was heated at 100 °C for 4 hours. After completion of reaction (TLC monitoring), the reaction mixture was diluted with water (50 mL) and extracted with ethyl acetate (100 mL x 2). The combined organic layer was washed with brine (50 mL), dried over anhydrous sodium sulphate, filtered and concentrated under reduced pressure. The crude product was purified by combiflash purifier and was eluted with 60% ethyl acetate in hexane to get 2-chloro-9-methyl-7-phenyl-5H,6H,7H,8H,9H-pyrimido[4,5-d][1, 3]diazepin-8-one (62) (0.8 g, Yield: 60.07%).
