Reaction Steps

230 mg (0.61 mmol) of (8S)-2-chloro-9-[2-(2-methyl-2H-pyrazol-3-yl)-2-oxoethyl]-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one and 107.90 mg (0.79 mmol) of (1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptane hydrochloride were used in the reaction. After purification by chromatography on silica gel (eluent: 60/40 DCM/MeOH), 160 mg of (8S)-9-[2-(2-methyl-2H-pyrazol-3-yl)-2-oxoethyl]-2-(1S,4S)-2-oxa-5-azabicyclo[2.2.1]hept-5-yl-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one are obtained, the characteristics of which are as follows:
