반응 단계
The product is prepared according to the procedure described in Example 18, using 300 mg of (8S)-2-morpholin-4-yl-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one (Example 1e), 47 mg of sodium hydride and 174 mg of 2,4-difluorobenzoyl chloride in 4 ml of tetrahydrofuran. After two successive purifications by silica chromatography (eluent: CH2Cl2/MeOH, gradient of 100/0 to 98/02 then 99/01), 24 mg of (8S)-9-[(2,4-difluorophenyl)carbonyl]-2-(morpholin-4-yl)-8-(trifluoromethyl)-6,7,8,9-tetra-hydro-4 H-pyrimido[1,2-a]pyrimidin-4-one are obtained in the form of a colourless lacquer, the characteristics of which are the following:
