Procedure

In a 25 ml round-bottomed flask, 71 mg of the sodium salt of [4-(2-hydroxymethylmorpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetic acid (example 25b, step 9b) and 38 mg of 4-chloro-2,3-dihydro-1H-indole are placed in 1 ml of dimethylformamide and 0.24 ml of pyridine, and then 57 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride are added. The reaction medium is stirred at ambient temperature for 20 h, then evaporated, water is added, and the resulting mixture is triturated. The solid formed is filtered off, and rinsed successively with water then with diisopropyl ether, with methylene chloride and then with pentane. The resulting solid is dried under vacuum for 2 h. (−)-2-[2-(4-Chloro-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-(2-hydroxymethylmorpholin-4-yl)-3H-pyrimidin-4-one (62 mg) is isolated in the form of a pulverulent solid (yield=63%).
