Reaction Steps

The product is prepared according to the procedure described in stage 1 of Example 2, but using 500 mg of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate (Example 1, stage 2), 425 mg of 2-amino-4,5-difluorophenol and 600 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride in a mixture of 4 ml of pyridine and 4 ml of dimethylformamide. 500 g of N-(4,5-difluoro-2-hydroxyphenyl)-2-[4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetamide are obtained in the form of a brown solid, the characteristics of which are the following:
