実験手順

In a microwave tube, 425 mg of (S)-2-morpholin-4-yl-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one (Example 1e) are introduced into 1 ml of dimethylformamide, 422 mg of tripotassium phosphate, 380 mg of copper iodide and 2 ml of iodobenzene. The mixture obtained is heated in a microwave oven for 30 minutes at 150° C. The reaction mixture is then centrifuged. The separated supernatant is then rinsed with ethyl acetate and then evaporated to dryness. The residue is taken up with ethyl acetate and the solution obtained is washed with water. The organic phase is separated and then dried over magnesium sulphate, filtered, and concentrated under vacuum. After purification by silica chromatography (gradient of 5% to 15% of the eluent CH2Cl2/MeOH/NH4OH 28% 38/17/2 in dichloromethane), 150 mg of (8S)-2-(morpholin-4-yl)-9-phenyl-8-(trifluoromethyl)-6,7,8,9-tetrahydro-4H-pyrimido[1,2-a]pyrimidin-4-one are obtained, the characteristics of which are the following:
