Participants

Reaction Steps

180 mg (0.511 mmol) of (8S)-2-chloro-9-(3,3-dimethyl-2-oxobutyl)-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one, 76.32 mg (0.563 mmol) of (1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptane hydrochloride and 179 μl (1.28 mmol) of triethylamine were used in the reaction. After purification by chromatography on silica gel (eluent A/B: DCM/MeOH, gradient A/B: t 0 min 0% B, t 15 min 4% B, t 18 min 4% B, t 33 min 10% B), 130 mg of (8S)-9-(3,3-dimethyl-2-oxobutyl)-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 were obtained, corresponding to the following characteristics:
