Reaction Steps

In a 50-ml eggplant flask provided with a magnetic stirrer were placed 3.04 g (20 mmol) of 5-amino-3-trifluoromethyl-1H-1,2,4-triazole, 3.06 g (22 mmol) of 3,4-difluorobenzonitrile, 2.76 g (20 mmol) of potassium carbonate and then 10 ml of N,N-dimethylformamide. The mixture was stirred at 60° C. for 6 hours. Thereto were added 50 ml of ethyl acetate and 50 ml of water to give rise to phase separation. The aqueous phase was extracted with 50 mol of ethyl acetate. The ethyl acetate phase was washed with water and then with a saturated aqueous sodium chloride solution. The ethyl acetate phase was dried over anhydrous sodium sulfate and then subjected to vacuum distillation to distill off ethyl acetate. To the residue was added 5 ml of toluene. The mixture was stirred with heating, cooled and then filtered to obtain 3.18 g of a crystal. Yield: 58.6%
