Procedure

150 mg of 4-fluoro-3,3-dimethyl-2,3-dihydro-1H-indole [reference example 2c] and 279 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride are added to a solution of 300 mg of sodium [1-methyl-4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate (obtained in step 2c of example 4c) in 5 ml of N,N-dimethylformamide and 5 ml of pyridine. The reaction mixture is stirred at ambient temperature for 16 hours and then 30 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 trituration from a mixture of ethyl acetate and diisopropyl ether, so as to give 260 mg of 2-[2-(4-fluoro-3,3-dimethyl-2,3-dihydro-1H-indol-1-yl)-2-oxoethyl]-3-methyl-6-(morpholin-4-yl)pyrimidin-4(3H)-one, the characteristics of which are the following:
