반응 단계
The product is prepared according to the procedure described in Example 22, using 100 mg of (8S)-2-morpholin-4-yl-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one (Example 1e), 214 mg of caesium carbonate and 75 mg of 1-(bromomethyl)-3,5-difluorobenzene in 2 ml of dimethylformamide. After purification by preparative HPLC/MS (Method C), 85 mg of (8S)-9-(3,5-difluorobenzyl)-2-(morpholin-4-yl)-8-(trifluoromethyl)-6,7,8,9-tetrahydro-4H-pyrimido[1,2-a]pyrimidin-4-one are obtained in the form of an oil, the characteristics of which are the following:
