Procedure

To a solution of 6-(6-methoxypyridin-3-yl)-4-methyl-2-(methylsulfinyl)pyrido[2,3-d]pyrimidin-7(8H)-one (147 mg, 0.445 mmol) in 1,4-dioxane (2.5 mL) was added methylamine (1.1 mL, 2.0 M in THF, 2.2 mmol). The mixture was sealed and heated at 110° C. microwave for 10 min. The mixture was concentrated under reduced pressure to give a solid. The crude solid was washed with water and EtOAc, recrystallized from DMSO/EtOAc to give the title compound (80 mg, 61%).
