Procedure

220 mg of 4-difluoromethoxy-2,3-dihydro-1H-indole (reference example 5d) and 364 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride are added to a solution of 327 mg of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate (obtained in step 2d of example 1d) in 7 ml of N,N-dimethylformamide and 7 ml of pyridine. The reaction mixture is stirred at ambient temperature for 16 hours, and then 15 ml of water are added and the mixture is extracted with ethyl acetate. The organic phase is washed successively with water and a saturated sodium chloride solution, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The residue is purified by silica column chromatography, elution being carried out with a mixture of dichloromethane and methanol (95/05: v/v), so as to give 24 mg of 2-{2-[4-(difluoromethoxy)-2,3-dihydro-1H-indol-1-yl]-2-oxoethyl}-6-(morpholin-4-yl)pyrimidin-4(3H)-one, the characteristics of which are the following:
