실험 절차

2-Methylpyridin-4-amine (0.28 g, 2.6 mmol) was placed in THF (5 mL) and cooled to −78° C. t-BuLi (1.5 mL, 2.6 mmol) was added dropwise, and the solution was warmed to 0° C. for 30 minutes. This solution was then added dropwise to a −78° C. THF solution (5 mL) of (S)-1-(2-(tert-butyldimethylsilyloxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-(methylsulfonyl)pyrimidin-4-yl)pyridin-2(1H)-one (0.070 g, 0.13 mmol). The reaction was stirred for an additional 30 minutes at −78° C., then poured into water, and extracted with DCM. The combined organic fractions were dried (MgSO4), filtered, and concentrated to give the crude product, which was purified by column chromatography (500:10-500:20 DCM/MeOH) to give the product (S)-1-(2-(tert-butyldimethylsilyloxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-((2-methylpyridin-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (0.028 g, 38% yield).
