Procedure

130 mg of 4-chloro-3,3-dimethyl-2,3-dihydro-1H-indole [which can be prepared according to Tet. Let. (1987) (28), 5291-5294] and 220 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride are added to a solution of 187 mg of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate (obtained in step 2c of example 1c) in 3 ml of N,N-dimethylformamide and 3 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-chloro-3,3-dimethyl-2,3-dihydro-1H-indol-1-yl)-2-oxoethyl]-6-(morpholin-4-yl)pyrimidin-4(3H)-one, the characteristics of which are the following:
