Reaction Steps

The product is prepared according to the procedure described in example 5, using 200 mg of sodium [1-methyl-4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate prepared in stage 1 of example 68, 220 mg of 3-cyclopropyl-4-fluoroaniline, and 180 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride in a mixture of 0.12 ml of pyridine and 2.5 ml of N,N-dimethylformamide. After extractions with ethyl acetate and silica column purification, eluent 90/10 CH2Cl2/MeOH, the residue is taken up with ml of diisopropyl ether, and the precipitate is spin-filter-dried and dried under vacuum, so as to obtain 69 mg of N-(3-cyclopropyl-4-fluorophenyl)-2-[1-methyl-4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetamide in the form of a yellow solid, the characteristics of which are the following:
