Participants

Reaction Steps

3-[8-(2,6-difluorophenyl)-2-(methylsulfonyl)-7-oxo-5,6,7,8-tetrahydropyrimido[4,5-d]pyrimidin-4-yl]-N,4-dimethylbenzamide (0.036 g, 0.074 mmol) was dissolved in THF (5 mL) and (3-aminopropyl)(1-methylethyl)amine (0.045 g, 0.37 mmol) was added. The reaction was stirred under argon overnight. The solvents were pumped off in vacuo, and the residue was flash chromatographed on silica gel (15 g) eluted with CH2Cl2 to 6:0.5:0.05, CH2Cl2:ethanol:NH4OH to give the title compound as a white amorphous solid. mp (dec) 153-157° C. LC-MS m/z 524.6 (M+H)+, 1.31 min (ret time).
