Procedure

3.32 g of 4-fluoro-2,3-dihydro-1H-indole and 5.56 g of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride are added to a solution of 5.4 g of the sodium salt of (4-methoxy-6-chloropyrimidin-2-yl)acetic acid in 50 ml of DMF and 4.3 ml of pyridine. The reaction medium is stirred at ambient temperature for one hour. 200 ml of ethyl acetate and 100 ml of water are added, and also 1N hydrochloric acid to pH=5-6. After settling out, the organic phase is dried over magnesium sulfate, filtered, and then concentrated under reduced pressure. The oil obtained is taken up with ethyl ether. The solid formed is filtered off so as to give 2.2 g of 1-(4-fluoro-2,3-dihydroindol-1-yl)-2-(4-methoxy-6-chloropyrimidin-2-yl)ethanone in the form of an orangey-colored solid, the characteristics of which are the following:
