Procedure

A solution of 4-Chloro-2-methylsulfanyl-8-(2,4-difluoro-phenyl)-8H-pyrido[2,3-d]pyrimidin-7-one (1.0 g, 2.9 mmol) in dichloromethane (50 mL) was mixed with m-CPBA (0.69 g, 4.4 mmol). The resultant mixture was stirred at room temperature for 10 minutes and concentrated under vacou. Flash chromatography (EtOAc/Hexane, 3: 1) then provided the title compound (1.02 g, 97%): MS (ES) m/z 356 (M+H)+; 1H-NMR(CDCl3) δ 2.84 (m, 3H), 7.01 (d, J=9.9 Hz, 1H), 7.09 (m, 2H), 7.29 (m, 1H), 8.16 (d, J=9.9 Hz, 1H).
