Versuchsvorschrift

(S)-1-(2-(tert-Butyldimethylsilyloxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-(methylsulfonyl)pyrimidin-4-yl)pyridin-2(1H)-one (0.100 g, 0.186 mmol) and 1,3-dimethyl-1H-pyrazol-4-amine (0.413 g, 3.72 mmol) were placed in s-BuOH (2 mL), heated to 110° C. overnight, 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 DCM/MeOH) to give the product (S)-1-(2-(tert-butyldimethylsilyloxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-((1,3-dimethyl-1H-pyrazol-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (0.070 g, 66.2% yield).
