Procedure

To a solution of 172 mg of the crude 2-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]-1,3-thiazole-5-carboxylic acid in 2.0 mL of THF was added 1.00 mL of a 4 M hydrogen chloride/ethyl acetate solution at room temperature, followed by stirring for 1 hour. 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 19 mg of 2-[3-(3-fluorophenyl)-4-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)piperidin-1-yl]-1,3-thiazole-5-carboxylic acid hydrochloride as a white solid.
