Reaction Steps

To a suspension of 2-aminomethyl-3H-pyrimido[4,5-d]pyrimidin-4-one (12 mg, 0.068 mmol) in THF (0.2 mL) and DIPEA (0.050 mL, 0.29 mmol) was added 3-phenyl-propionyl chloride (14 mg, 0.08 mmol) at ambient temperature. The reaction mixture was stirred one hour, evaporated and purified by column chromatography (silica gel, EtOAc/MeOH, 1/1) to yield N-(4-oxo-3,4-dihydro-pyrimido[4,5-d]pyrimidin-2-ylmethyl)-3-phenyl-propionamide as a white solid (0.8 mg, 3.8%). MS (m/e): 310.3 [M+H+].
