HCID 118194450(8S)-2-chloro-9-[2-(2-cyclopropylmethoxypyrimidin-5-yl)-2-oxoethyl]-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one

実験手順

180 mg (0.71 mmol) of (8S)-2-chloro-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one and 211.66 mg (0.78 mmol) of 2-bromo-1-(2-cyclopropylmethoxypyrimidin-5-yl)ethanone were used in the reaction. After purification by chromatography on silica gel (eluent: 80/20 DCM/MeOH), 160 mg of (8S)-2-chloro-9-[2-(2-cyclopropylmethoxypyrimidin-5-yl)-2-oxoethyl]-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one are obtained, the characteristics of which are as follows:
