Participants

Reaction Steps

To a mixture of 3-(2,6-dichloro-3,5-dimethoxyphenyl)-1-methyl-7-(methylsulfonyl)-3,4-dihydropyrimido[4,5-d]pyrimidin-2(1H)-one (450 mg, 1.01 mmol) and 2-methyl-6-nitroaniline (230 mg, 1.51 mmol) in 5 mL of N,N-dimethylformamide was added potassium tert-butanolate (339 mg, 3.02 mmol) at RT and stirred for 0.5 h. LCMS showed the reaction was completed. The mixture was quenched by 80 mL of water, and the precipitate was collected via the filtration and dried to give the title compound (290 mg, 56%) as a yellow solid, which was directly used in the next step without further purification. MS (ES+) C22H20Cl2N6O5 requires: 518, 520. found: 519, 521 [M+H]+.
