Procedure

tert-Butyl (3R,5S)-3-(1-hydroxyethyl)-5-[({5-[(2-methoxyethoxy)methyl]-1-(2-methylphenyl)-1H-1,2,3-triazol-4-yl}carbonyl)(2-methylpropyl)amino]piperidine-1-carboxylate (319 mg) was dissolved in 10% hydrogen chloride-methanol (4 ml), and the mixture was stirred at room temperature for 13 hr. The reaction mixture was concentrated under reduced pressure, and the residue was subjected to reversed-phase preparative HPLC and the eluted fraction was concentrated under reduced pressure. The residual aqueous layer was neutralized with 3.5M aqueous potassium carbonate solution and extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, and the solvent was concentrated under reduced pressure. The residue and fumaric acid (27.9 mg) were dissolved in methanol (2 ml), and the solvent was evaporated under reduced pressure to give the object product (254 mg).
