Participants

Reaction Steps

To a solution of 1-(2-iodo-4-{[(2,2,2-trifluoroethyl)amino]carbonyl}phenyl)-1H-1,2,3-triazole-4-carboxylic acid (2.08 g, 4.73 mmol) obtained in Example 379d) in DMF (20 ml) were sequentially added cyclopropylamine (500 mg), triethylamine (1.0 ml), HOBt (360 mg) and WSC (1.4 g), and the reaction mixture was stirred at room temperature overnight. The solvent was evaporated under reduced pressure, and the residue was dissolved in ethyl acetate and washed with saturated aqueous sodium hydrogen carbonate solution. 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=1/20 to 1/1) to give the title compound as a colorless powder (1.66 g, 73%).
