Procedure

To a suspension of N-cyclopropyl-1-{4-[(ethylamino)carbonyl]-2-[(6-hydroxyhexyl)oxy]phenyl}-1H-1,2,3-triazole-4-carboxamide (0.14 g) obtained in Example 183 in dichloromethane (10 ml) was added DAST (0.10 ml) at −78° C. The reaction mixture was slowly allowed to warm to room temperature and stirred overnight. Saturated aqueous sodium hydrogen carbonate solution was added to the reaction mixture, and the organic layer was separated. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column (ethyl acetate) and recrystallized from ethyl acetate-diisopropyl ether to give the title compound as a white powder (0.02 g, 15%).
