실험 절차

4′-Trifluoromethyl-biphenyl-carboxylic acid (5.0 g) was dissolved in dimethylformamide (50 mL), and to this solution were added at room temperature 4-amino-1-benzylpiperidine (3.55 g), 1-hydroxybenzotriazole hydrate (3.0 g) and 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (3.58 g). The mixture was stirred at room temperature overnight, and the reaction solution was concentrated in vacuo to precipitate crystals. The crystals were washed successively with saturated aqueous sodium bicarbonate and water, and dried in vacuo to give the title compound (7.42 g).
