Reaction Steps
To a solution of 1-tert-butyl 3-methyl (3R,5S)-5-[{[5-(4-methoxybutyl)-1-phenyl-1H-1,2,3-triazol-4-yl]carbonyl}(2-methylpropyl)amino]piperidine-1,3-dicarboxylate (1.715 g) in methanol (10 ml) was added 4N aqueous sodium hydroxide solution (10 ml), and the mixture was stirred at 65° C. for 30 min. The solvent was concentrated under reduced pressure, and the residue was neutralized with 10% aqueous citric acid solution. The mixture was extracted with ethyl acetate (20 ml×2) and the extract was dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the object product (1.56 g) as an amorphous compound.
