Compound 109 was prepared from compound 8 according to Method G. Compound 109 was then converted to compound 110 according to the following procedure: The mixture of (S)-ethyl 2-amino-4-((1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carboxylate (300 mg, 0.65 mmol) and 2-methoxypyridin-4-yl)boronic acid (149 mg, 0.98 mmol) in 1,4-dioxane:water (3:1, 12 mL) was degassed and backfilled with argon (three cycles). To this mixture, 2-dicyclohexylphosphino-2′,6′-diisopropoxybiphenyl (121 mg, 0.26 mmol), palladium(II) acetate (29 mg, 0.13 mmol), and Na2CO3 (207 mg, 1.95 mmol) were added sequentially. The resulting mixture was degassed and backfilled with argon (three cycles), and then stirred at 120° C. for 3 h. The mixture was allowed to cool to RT, and then partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by ISCO column chromatography (silica gel cartridge, 0-10% MeOH/DCM) to afford the product 110, (S)—ethyl 2-amino-4-((1-(8-(2-methoxypyridin-4-yl)-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carboxylate.
