1-{4-[(Ethylamino)carbonyl]phenyl}-5-[(E)-2-phenylvinyl]-1H-1,2,3-triazole-4-carboxylic acid (264 mg, 0.728 mmol) obtained in Example 106b), HOBt (49.7 mg, 0.364 mmol, 0.5 eq.) and cyclopropylamine (0.068 ml, 0.947 mmol, 1.3 eq.) were dissolved in acetonitrile-DMF (3:1, 4 ml), WSC (171 mg, 0.874 mmol, 1.2 eq.) was added, and the mixture was stirred at room temperature for 13 hr. Water (10 ml) was added to the reaction mixture and the mixture was stirred. The precipitate was collected by filtration, washed with water and dried to give the title compound as a white powder (258 mg, 0.643 mmol, 88.3%).
