Procedure

tert-Butyl (3S,5R)-3-[{[5-(hydroxymethyl)-1-phenyl-1H-1,2,3-triazol-4-yl]carbonyl}(2-methylpropyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (205 mg), phenol (70 mg) and triphenylphosphine (190 mg) were dissolved in toluene (5 ml), diisopropyl azodicarboxylate (40% toluene solution, 365 mg) was added, and the mixture was stirred at room temperature for 12 hr. The reaction mixture was poured into saturated brine, 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 (10:90-100:0) was concentrated under reduced pressure to give the object product (344 mg).
