Reaction Steps

To 3-[8-(2,6-difluorophenyl)-2-(methylsulfonyl)-7-oxo-5,6,7,8-tetrahydropyrimido[4,5-d]pyrimidin-4-yl]-4-methyl-N-propylbenzamide (497 mg, 1.0 mmol) in dichloromethane (20 mL) was added 1,3-propyldiamine (0.251 mL, 3.0 mL). The mixture was stirred over night. The mixture was concentrated and separated by flash chromatography to afford the title compound (395 mg, 78%). LC-MS m/z 510 (M+H)+.
