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 238 mg (1.07 mmol) of 4-(2-diethylaminoethoxy)benzylamine was heated at 170° C. for 30 minutes. The product was purified by flash column chromatography using dichloromethane/methanol/water/acetic acid (120:14:3:2) for the elution. Product-containing fractions were combined and evaporated to give 40 mg (29%) of 3-(2,6-dichlorophenyl)-7-[4-[2-(diethylamino)ethoxy]benzylamino]-3,4-dihydro-1-methylpyrimido[4,5-d]pyrimidin-2(1H)-one as a white solid of melting point 137-138° C.
