Using the general procedure above, 3-(3,5-dimethoxy-phenyl)-7-methanesulfinyl-3,4-dihydro-pyrimido[4,5-d]pyrimidin-2(1H)-one and 0.1354 g (0.791 mmol) of 4-(4-methyl-piperazin-1-yl)-butylamine were reacted. The residue was chromatographed over silica gel, eluting with ethyl acetate/ethanol/triethylamine (9:2:1 v/v/v) then ethyl acetate/ethanol/triethylamine (9:3:2 v/v/v) to give 0.0401 g (31%) of the title compound: HPLC=99% pure.
