Procedure

tert-Butyl (3S,5R)-3-[{[1-(2-fluorophenyl)-5-(4-methoxybutyl)-1H-1,2,3-triazol-4-yl]carbonyl}(2-methylpropyl)amino]-5-(hydroxymethyl)piperidine-1-carboxylate (165 mg) and triethylamine (215 μl) were dissolved in THF (4 ml), and methanesulfonyl chloride (60 μl) was added under ice-cooling. The mixture was stirred at 0° C. for 2 hr, and sodium methoxide (28% methanol solution, 600 mg) and methanol (2 ml) were added, and the mixture was further stirred at 75° C. for 3 hr. The mixture was cooled to room temperature and diluted with water and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate-hexane (5:95-80:20) was concentrated under reduced pressure to give the object product (142 mg).
