To a solution of 168 mg of 6-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]hexanoic 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 solvent was removed by distillation under reduced pressure. The residue was purified by reverse phase silica gel column chromatography (acetonitrile-0.001 M hydrochloric acid) to obtain 70 mg of 6-[3-(3-fluorophenyl)-4-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)piperidin-1-yl]hexanoic acid dihydrochloride as a pale yellow solid.
