Reaction Steps

The product is prepared according to the procedure described in stage k of Example 1, using 95 mg of (2S)-2-methyl-7-(morpholin-4-yl)-2-(trifluoromethyl)-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one (Example 1j) and 101 mg of 6-(bromomethyl)-4-chloro-2-(trifluoromethyl)quinoline, replacing the sodium hydride with 203 g of caesium carbonate. After purification by preparative HPLC/MS (method C), 40 mg of (2S)-1-{[4-chloro-2-(trifluoromethyl)quinolin-6-yl]methyl}-2-methyl-7-(morpholin-4-yl)-2-(trifluoromethyl)-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one, in the form of a trifluoroacetic acid salt, are obtained in the form of a beige powder, the characteristics of which are the following:
