Participants

Reaction Steps

1-{4-[(Ethylamino)carbonyl]phenyl}-5-(5-phenylpentyl)-1H-1,2,3-triazole-4-carboxylic acid (392 mg, 0.964 mmol) obtained in Example 101b), HOBt (67.3 mg, 0.482 mmol, 0.5 eq.) and cyclopropylamine (0.090 ml, 1.25 mmol, 1.3 eq.) were dissolved in acetonitrile-DMF (2:1, 6 ml), WSC (226 mg, 1.16 mmol, 1.2 eq.) was added, and the mixture was stirred at room temperature for 13.5 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 methanol-water (1:1) and dried to give the title compound as a white powder (412 mg, 0.925 mmol, 95.9%).
