Versuchsvorschrift

The product is prepared according to the procedure described in Example 1, using 100 mg of (S)-2-methyl-7-morpholin-4-yl-2-trifluoromethyl-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-5-one (Example 1j) and 143 mg of (2-bromoethyl)phenyl ether, replacing the sodium hydride with caesium carbonate. After purification by silica column chromatography (eluent: dichloromethane/methanol 97/03), 124 mg of (S)-2-methyl-7-morpholin-4-yl-1-(2-phenoxyethyl)-2-trifluoromethyl-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-5-one are obtained, the characteristics of which are the following:
