Reaction Conditions

Reaction Steps

A mixture of 4-{[3-(methylcarbamoyl)phenyl]amino}-2-(methylsulfinyl)-6-oxo-1,6-dihydropyrimidine-5-carboxamide (Preparation Example 311) (234 mg), 1-(aminomethyl)cyclohexaneamine (172 mg) and NMP (2 mL) was stirred at 80° C. for 30 minutes. After cooling, the reaction liquid was diluted with ethyl acetate, and the precipitated solid was collected by filtration. This solid was heated with ethanol-water and washed to give 2-{[(1-aminocyclohexyl)methyl]amino}-4-{[3-(methylcarbamoyl)phenyl]amino}-6-oxo-1,6-dihydropyrimidine-5-carboxamide (215 mg) as a white solid.
