Reaction Steps
In a 50-ml eggplant flask provided with a magnetic stirrer were placed 1.37 g (10 mmol) of 3-trifluoromethyl-1H-1,2,4-triazole, 1.32 g (3.33 mmol) of 2,4-dimethylphenylboroxine, 64 mg (1 mmol) of a copper powder, 0.8 g (10 mmol) of pyridine and then 5 ml of N,N-dimethylformamide. The mixture was stirred at 50° C. for 4 hours. Thereto were added 30 ml of ethyl acetate and 3% hydrochloric acid to give rise to phase separation. The aqueous phase was extracted with 30 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 obtain a title compound as 2.3 g of a crystal. Yield: 95%
