Triethylamine → rac-N-[(1R,2S,4S)-bicyclo[2.2.1]hept-2-yl]-5-(morpholin-4-ylcarbonyl)-4-(trifluoromethyl)pyrimidin-2-amine

Participants

Reaction Steps

A mixture of 4-{[2-chloro-4-(trifluoromethyl)pyrimidin-5-yl]carbonyl}morpholine (150 mg), rac-(1S,2R,4R)-bicyclo[2.2.1]heptan-2-amine hydrochloride (300 mg), triethylamine (354 μL), and 1,4-dioxane (1.5 mL) was stirred at room temperature for 3 hours. To the reaction mixture was added water and the aqueous layer was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate), and the obtained colorless oil was solidified from hexane-ethyl acetate to obtain rac-N-[(1R,2S,4S)-bicyclo[2.2.1]hept-2-yl]-5-(morpholin-4-ylcarbonyl)-4-(trifluoromethyl)pyrimidin-2-amine (132 mg) as a white solid.
