Procedure

To a solution of 1-tert-butyl 3-methyl(3R,5S)-5-[{[5-(4 methoxybutyl)-1-(2-methylphenyl)-1H-1,2,3-triazol-4-yl]carbonyl}(2-methylpropyl)amino]piperidine-1,3-dicarboxylate (1.47 g) in methanol (10 ml) was added 4N aqueous sodium hydroxide solution (5 ml), and the mixture was stirred at 50° C. for 30 min. The solvent was concentrated under reduced pressure, and the residue was neutralized with 10% aqueous citric acid solution, extracted with ethyl acetate (30 ml×2) and the extract was dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the object product (1.3 g) as an amorphous compound.
