Vorschrift

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-dihydro-1H-imidazo[1,2-a]pyrimidin-5-one (Example 1j) and 103 mg of 3-(bromomethyl)-5-chloro-1-benzothiophene, replacing the sodium hydride with caesium carbonate. After purification by preparative HPLC/MS (method C), 49 mg of (2S)-1-[(5-chloro-1-benzothiophen-3-yl)methyl]-2-methyl-7-(morpholin-4-yl)-2-(trifluoromethyl)-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one are obtained in the form of a brown solid, the characteristics of which are the following:
