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)(1,1-dimethylethyl)amine (0.045 g, 0.37 mmol) was added. The reaction was stirred under argon for 2 days. 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)166-170° C. LC-MS m/z 538 (M+H)+, 1.38 min (ret time).
