Participants

Reaction Steps

250 mg (0.63 mmol) of (8S)-2-chloro-9-(1-methyl-1H-indazol-3-ylmethyl)-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one and 102.26 mg (0.75 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), 230 mg of (8S)-9-(1-methyl-1H-indazol-3-ylmethyl)-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:
