Reaction Steps

A mixture of 100 mg (0.26 mmol) of 3-(2,6-dichlorophenyl)-3,4-dihydro-7-methanesulfonyl-1-methylpyrimido[4,5-d]pyrimidin-2(1H)-one and 140 mg (1 mmol) of 2-(4-aminophenyl)ethylamine was heated at 70° C. for 20 minutes. The product was purified by flash column chromatography using 5% methanol in dichloromethane for the elution. Product-containing fractions were combined and evaporated. The residue was recrystallized from ethyl acetate and 3 mg (3%) of 7-[2-(4-aminophenyl)ethylamino]-3-(2,6-dichlorophenyl)-3,4-dihydro-1-methylpyrimido[4,5-d]pyrimidin-2(1H)-one were isolated as a yellow solid of melting point 174-175° C.
