実験手順
To a mixture of rac-2-[(1R,2R,4S)-bicyclo[2.2.1]hept-2-ylamino]-4-(trifluoromethyl)pyrimidine-5-carboxylic acid (150 mg) and N,N-dimethyl formamide (3.0 mL) were added 1-(tetrahydro-2H-pyran-4-yl)methylamine (69 mg), 1-hydroxybenzotriazole (81 mg), and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (115 mg) in this order at room temperature, and then the mixture was stirred at room temperature for 5 hours. To the reaction mixture was added water, followed by extraction with ethyl acetate. The organic layer was washed with water, a saturated aqueous sodium hydrogen carbonate solution, and saturated brine in this order, and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and then the obtained residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate). The obtained colorless oily substance was solidified using ethanol-water to obtain rac-2-[(1R,2R,4S)-bicyclo[2.2.1]hept-2-ylamino]-N-(tetrahydro-2H-pyran-4-ylmethyl)-4-(trifluoromethyl)pyrimidine-5-carboxamide (173 mg) as a white solid.
