Reaction Steps

(±)-2-[2-(2-Ethyl-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-morpholin-4-yl-3H-pyrimidin-4-one is prepared by following the procedure described in example 1c using 0.40 g of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate, 0.25 g of 2-ethylindoline [which can be prepared according to patent WO2009065920] and 0.39 g of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride in a mixture of 250 ml of pyridine and 6.5 ml of N,N-dimethylformamide. After purification by chromatography on a 25 g cartridge of 15-40 μm silica, elution being carried out successively with 99/1 then 98/2 and 97/3 v/v dichloromethane/methanol mixtures, at a flow rate of 30 ml/min, 0.35 g of (±)-2-[2-(2-ethyl-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-morpholin-4-yl-3H-pyrimidin-4-one is obtained in the form of a white foam, the characteristics of which are the following:
