Reaction Steps
WSC•monohydrochloride (130 mg), HOBt (110 mg) and formic hydrazide (60 mg) were sequentially added to a solution of 5-chloro-2-(1-methyl-1-{4-methyl-5-[2-(trifluoromethyl)phenyl]-4H-1,2,4-triazol-3-yl}ethoxy)benzoic acid (300 mg) in DMF (6 ml), followed by stirring at room temperature for 4 hours. Water was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was sequentially washed with saturated aqueous sodium bicarbonate solution, water and then saturated brine in this order, and dried over anhydrous magnesium sulfate, and the solvent was then evaporated under reduced pressure to obtain 5-chloro-N′-formyl-2-(1-methyl-1-{4-methyl-5-[2-(trifluoromethyl)phenyl]-4H-1,2,4-triazol-3-yl}ethoxy)benzohydrazide (230 mg).
