Procedure

5-(Cyclohexylmethyl)-1-{4-[(ethylamino)carbonyl]phenyl}-1H-1,2,3-triazole-4-carboxylic acid (357 mg, 1.00 mmol) obtained in Example 102b), HOBt (68.2 mg, 0.500 mmol, 0.5 eq.) and cyclopropylamine (0.093 ml, 1.30 mmol, 1.3 eq.) were dissolved in acetonitrile-DMF (2:1, 4.5 ml), WSC (215 mg, 1.10 mmol, 1.1 eq.) was added, and the mixture was stirred at room temperature for 14 hr. Water was added to the reaction mixture, and the obtained suspension was diluted with 2% aqueous sodium hydrogen carbonate solution. The precipitate was collected by filtration, washed with water and dried to give the title compound as a white powder (363 mg, 0.918 mmol, 91.8%).
