Reaction Steps

The product is prepared according to the procedure described in Example 12, using 140 mg of (S)-2-morpholin-4-yl-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one (Example 1e) and 0.66 ml of 1-fluoro-4-iodobenzene. After purification by silica chromatography (gradient of 5% to 15% of the eluent CH2Cl2/MeOH/NH4OH 28% 38/17/2 in dichloromethane), 125 mg of (8S)-9-(4-fluorophenyl)-2-(morpholin-4-yl)-8-(trifluoromethyl)-6,7,8,9-tetrahydro-4H-pyrimido[1,2-a]pyrimidin-4-one are obtained, the characteristics of which are the following:
