Procedure
To a solution of 5-[(1E)-prop-1-en-1-yl]-1-(4-{[(2,2,2-trifluoroethyl)amino]carbonyl}phenyl)-1H-1,2,3-triazole-4-carboxylic acid (1.96 g) obtained in Example 1215a) in DMF (22 ml) were successively added cyclopropylamine (0.46 ml), triethylamine (0.92 ml), HOBt (1.01 g) and WSC (1.27 g), and the reaction mixture was stirred at room temperature for 2.5 hr. Water and ethyl acetate were 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/hexane=1/1 to ethyl acetate) and recrystallized from ethyl acetate-diisopropyl ether to give the title compound as a white powder (1.13 g, 52%).
