Procedure

tert-Butyl(3S,5R)-3-[{[1-(2-fluorophenyl)-5-(hydroxymethyl)-1H-1,2,3-triazol-4-yl]carbonyl}(2-methylpropyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (210 mg) and triethylamine (150 μl) were dissolved in THF (4 ml), and methanesulfonyl chloride (45 μl) was added under ice-cooling. The mixture was stirred at 0° C. for 4 hr, sodium methoxide (28% methanol solution, 350 mg) and methanol (4 ml) were added and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with water and 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 (10:90-100:0) was concentrated under reduced pressure to give the object product (195 mg).
