To a solution of 88 mg of 3-({[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]carbonyl}oxy)benzoic acid in 2.0 mL of ethyl acetate was added 1.00 mL of a 4 M hydrogen chloride/ethyl acetate solution at room temperature, followed by stirring for 2 hours. The resulting precipitate was collected by filtration, and dried under reduced pressure to obtain 22 mg of 3-({[3-(3-fluorophenyl)-4-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)piperidin-1-yl]carbonyl}oxy)benzoic acid hydrochloride as a white solid.
