The product is prepared according to the procedure described in stage k of Example 1, using 100 mg of (2S)-2-methyl-7-(morpholin-4-yl)-2-(trifluoromethyl)-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one (Example 1j) and 87 mg of 1-(2-bromoethyl)-3-chlorobenzene, replacing the sodium hydride with 214 mg of caesium carbonate. After purification by preparative HPLC/MS (method C), 38 mg of (2S)-1-[2-(3-chlorophenyl)ethyl]-2-methyl-7-(morpholin-4-yl)-2-(trifluoromethyl)-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)one are obtained in the form of an oil, the characteristics of which are the following:
