Procedure
A mixture of 7-methanesulfonyl-1-methyl-3-(2-methyl-5-nitro-phenyl)-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one (148 mg, 0.39 mmol) and 3-dimethylaminoaniline (530 mg, 3.9 mmol) is stirred for 1 hour at 130° C. The mixture is cooled down to room temperature and suspended in methanol. The precipitate is collected and washed with methanol to give 7-(3-dimethylamino-phenylamino)-1-methyl-3-(2-methyl-5-nitro-phenyl)-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one (98 mg, 58%) as a yellow solid.
