Participants

Reaction Steps

210 mg (0.49 mmol) of (8S)-9-(2-benzo[1,2,3]thiadiazol-5-yl-2-oxoethyl)-2-chloro-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one and 79.50 mg (0.58 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), 100 mg of (8S)-9-(2-benzo[1,2,3]thiadiazol-5-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:
