Procedure

To the compound 4-chloro-8-(2,6-difluorophenyl)-2-(methylsulfinyl)-pyrido[2,3-d]pyrimidin-7(8H)-one (1.59 g, 4.47 mmol) in dichloromethane (89.4 mL) were added N,N-diethyl-1,3-propanediamine (0.845 mL, 5.36 mol) and triethylamine (1.26 uL, 8.94 mmol). The mixture was stirred at rt overnight. Some white precipitate was formed during the reaction. Filtration followed by wash with ethyl acetate/dichloromethane/methanol afforded the title compound (1.028 g, 60%). LC-MS m/z 383 (M+H)+.
