INHIBITORS OF HUMAN IMMUNODEFICIENCY VIRUS REPLICATION FIELD OF THE INVENTION The invention relates to compounds, compositions, and methods for the treatment of human immunodeficiency virus (HIV) infection. More particularly, the invention provides novel inhibitors of HIV, pharmaceutical compositions containing such compounds, and methods for using these compounds in the treatment of HIV infection. The invention also relates to methods for making the compounds hereinafter described. BACKGROUND OF THE INVENTION Acquired immunodeficiency syndrome (AIDS) is the result of infection by HIV. HIV continues to be a major global public health issue. In 2015, an estimated 36.7 million people were living with HIV (including 1.8 million children) – a global HIV prevalence of 0.8%. The vast majority of this number live in low- and middle- income countries. In the same year, 1.1 million people died of AIDS-related illnesses. Current therapy for HIV-infected individuals consists of a combination of approved anti-retroviral agents. Close to four dozen drugs are currently approved for HIV infection, either as single agents, fixed dose combinations or single tablet regimens; the latter two containing 2-4 approved agents. These agents belong to a number of different classes, targeting either a viral enzyme or the function of a viral protein during the virus replication cycle. Thus, agents are classified as either nucleotide reverse transcriptase inhibitors (NRTIs), non-nucleotide reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), integrase strand transfer inhibitors (INSTIs), or entry inhibitors (one, maraviroc, targets the host CCR5 protein, while the other, enfuvirtide, is a peptide that targets the gp41 region of the viral gp160 protein). In addition, a pharmacokinetic enhancer (cobicistat or ritonavir) can be used in combinations with antiretroviral agents (ARVs) that require boosting. Despite the armamentarium of agents and drug combinations, there remains a medical need for new anti-retroviral agents. High viral heterogeneity, drug-associated toxicity, tolerability problems, and poor adherence can all lead to treatment failure and may result in the selection of viruses with mutations that confer resistance to one or more antiretroviral agents or even multiple drugs from an entire class (Beyrer, C., Pozniak A. HIV drug resistance – an emerging threat to epidemic control. N. Engl. J. Med. 2017, 377, 1605-1607; Gupta, R. K., Gregson J., et al. HIV-1 drug resistance before initiation or re-initiation of first-line antiretroviral therapy in low-income and middle-income countries: a systematic review and meta-regression analysis. Lancet Infect. Dis. 2017, 18, 346-355; Zazzi, M., Hu, H., Prosperi, M. The global burden of HIV-1 drug resistance in the past 20 years. PeerJ. 2018, DOI 10.7717/peerj.4848). As a result, new drugs are needed that are easier to take, have high genetic barriers to the development of resistance and have improved safety over current agents. In this panoply of choices, novel mechanisms of action (MOAs) that can be used as part of the preferred antiretroviral therapy (ART) can still have a major role to play since they should be effective against viruses resistant to current agents. Certain potentially therapeutic compounds have now been described in the art and set forth in Blair, Wade S. et.al. Antimicrobial Agents and Chemotherapy (2009), 53(12), 5080- 5087, Blair, Wade S. et al. PLoS Pathogens (2010), 6(12), e1001220, Thenin-Houssier, Suzie; Valente, Susana T. Current HIV Research, 2016, 14, 270-282, and PCT Patent applications with the following numbers: WO 2012065062, WO 2013006738, WO 2013006792, WO 2014110296, WO 2014110297, WO 2014110298, WO 2014134566, WO 2015130964, WO2015130966, WO 2016033243, WO2018035359, WO2018203235, WO 2019161017, and WO 2019161280. What is now needed in the art are additional compounds which are novel and useful in the treatment of HIV. Additionally, these compounds should provide advantages for pharmaceutical uses, for example, with regard to one or more of their mechanisms of action, binding, inhibition efficacy, target selectivity, solubility, safety profiles, bioavailability or reduced frequency of dosing. Also needed are new formulations and methods of treatment which utilize these compounds.

Preparation of Example 72: N-((S)-1-((1P)-1-(4-chloro-3-(methylsulfonamido)-1-(2,2,2- trifluoroethyl)-1H-indazol-7-yl)-6-oxo-4-(6-(trifluoromethyl )pyridin-2-yl)-1,6-dihydropyrimidin- 2-yl)-2-(3,5-difluorophenyl)ethyl)-2-((3bS,4aR)-3-(difluorom ethyl)-5,5-difluoro-3b,4,4a,5- tetrahydro-1H-cyclopropa[3,4]cyclopenta[1,2-c]pyrazol-1-yl)a cetamide. The title compound was prepared according to General Procedure D using 2-(tributylstannyl)- 6-(trifluoromethyl)pyridine as the coupling partner. The experiment afforded the title compound, N-((S)-1-((1P)-1-(4-chloro-3-(methylsulfonamido)-1-(2,2,2-tr ifluoroethyl)-1H- indazol-7-yl)-6-oxo-4-(6-(trifluoromethyl)pyridin-2-yl)-1,6- dihydropyrimidin-2-yl)-2-(3,5- difluorophenyl)ethyl)-2-((3bS,4aR)-3-(difluoromethyl)-5,5-di fluoro-3b,4,4a,5-tetrahydro-1H- cyclopropa[3,4]cyclopenta[1,2-c]pyrazol-1-yl)acetamide. The sample was analyzed using LCMS Method B: retention time = 3.29 min.; observed ion = 967.9 (M+H). IUPAC Chemical Names: The IUPAC chemical names for each example are listed below. At this time these names are not recognized by common software such tools such as ChemDraw or JChem. Therefore, the chemical names used throughout the Examples section above were generated with ChemDraw and then appended with the correct P/M designation. The chemical names above can be converted to chemical structures using ChemDraw after the P/M nomenclature—e.g., “(1P)-“— is removed.

BIOLOGICAL METHODS HIV cell culture assay - MT-2 cells, 293T cells and the proviral DNA clone of NL4-3 virus were obtained from the NIH AIDS Research and Reference Reagent Program. MT-2 cells were propagated in RPMI 1640 media supplemented with 10% heat inactivated fetal bovine serum (FBS), 100 ^g/ml penicillin G and up to 100 units/mL streptomycin. The 293T cells were propagated in DMEM media supplemented with 10% heat inactivated FBS, 100 ^g/mL penicillin G and 100 ^g/mL streptomycin. A recombinant NL4-3 proviral clone, in which a section of the nef gene was replaced with the Renilla luciferase gene, was used to make the reference virus used in these studies. The recombinant virus was prepared through transfection of the recombinant NL4-3 proviral clone into 293T cells using Transit-293 Transfection Reagent from Mirus Bio LLC (Madison, WI). Supernatent was harvested after 2-3 days and the amount of virus present was titered in MT-2 cells using luciferase enzyme activity as a marker by measuring luciferase enzyme activity. Luciferase was quantitated using the EnduRen Live Cell Substrate from Promega (Madison, WI). Antiviral activities of compounds toward the recombinant virus were quantified by measuring luciferase activity in MT-2 cells infected for 4-5 days with the recombinant virus in the presence of serial dilutions of the compound. The 50% effective concentration (EC50) was calculated by using the exponential form of the median effect equation where (Fa) = 1/[1+ (ED ₅₀ /drug conc.) ^m ] (Johnson VA, Byington RT. Infectivity Assay. In Techniques in HIV Research. ed. Aldovini A, Walker BD. 71-76. New York: Stockton Press.1990). Curve fitting and analysis were performed with ActivityBase XE Runner software version 9.1.0.4 using model 203 (ID Business Solutions, LTD, Guildford, UK). Compound cytotoxicity and the corresponding CC50 values were determined using the same protocol as described in the antiviral assay except that uninfected cells were used. Cytotoxicity was assessed on day 4 in uninfected MT2 cells by using a XTT (2,3-bis[2- Methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxyanili de inner salt)-based colorimetric assay (Sigma-Aldrich, St Louis, Mo).
