Reaction Steps

In a 25-ml eggplant flask provided with a magnetic stirrer was placed 3.3 g (9.3 mmol) of 5-(5-amino-3-trifluoromethyl-1H-1,2,4-triazol-1-yl)-2,4-dimethylbenzenesulfonyl chloride, followed by addition of 3.27 g (50 mmol) of zinc, 10 ml of ethanol and 5 ml (50 mmol) of 35% hydrochloric acid. The mixture was stirred at room temperature for 15 minutes. Then, the mixture was refluxed with heating, for 3 hours. The mixture was cooled to room temperature. Thereto were added 30 ml of water and 30 ml of ethyl acetate to give rise to phase separation. The aqueous phase was extracted with 30 ml of ethyl acetate. The ethyl acetate phase was washed with water and then with a saturated aqueous sodium chloride solution, and dried over anhydrous sodium sulfate. Vacuum distillation was conducted to distil off ethyl acetate to obtain a title compound as 1.9 g of oil.
