実験手順
To the compound 4-chloro-8-(2,6-difluorophenyl)-2-(methylsulfinyl)pyrido[2,3-d]pyrimidin-7(8H)-one (1.39 g, 3.9 mmol) in dichloromethane (80 mL) were added 4-methyl-1,4′-bipiperidine (0.75 g, 5.85 mol) and triethylamine (1.03 mL, 11.7 mmol). The mixture was stirred at −20° C. overnight. Filtration followed by concentration, the crude was purified with flash chromatography to afford the title compound (0.904 g, 51%). LC-MS m/z 474 (M+H)+.
