Reaction Steps

Charged a flask with 6-bromo-8-methyl-2-(methylsulfonyl)pyrido[2,3-d]pyrimidin-7(8H)-one (0.910 g, 2.86 mmol, prepared by reference in Scheme 6E) and 10.0 mL IPA. Chilled suspension to 0° C. and treated with methylamine 33% wt. solution in ethanol (1.78 ml, 14.3 mmol). After addition was complete, the bath was removed and the reaction mixture was allowed to warm to ambient temperature and stirred overnight. The crude reaction mixture was filtered and washed with ethanol (2×30 mL) and air-dried to afford a white microcrystalline solid: 6-bromo-8-methyl-2-(methylamino)pyrido[2,3-d]pyrimidin-7(8H)-one (0.637 g, 82.8% yield). MS (M+H)+ 269, 271.
