In a microwave tube, 300 mg of ethyl [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate prepared in stage 1 of Example 1 are introduced into 1 ml of N,N-dimethylformamide, 623 mg of 2-fluoroaniline and 378 mg of potassium tert-butoxide. 2 ml of N,N-dimethylformamide are then added. The tube is then microwave-heated at 150° C. for 20 minutes. The reaction mixture is concentrated under reduced pressure. 30 ml of water and 10 ml of ethyl acetate are added and the resulting mixture is thus stirred for 1 h 30. The precipitate formed is filtered off and rinsed with ethyl acetate, ethyl ether and then petroleum ether. The solid obtained is dried in a rotary evaporator and 93 mg of N-(2-fluorophenyl)-2-[4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetamide are thus obtained in the form of a white solid, the characteristics of which are the following:
