실험 절차

8 g of pulverised KOH are added to 10.9 g of p-aminophenol in 120 ml of dimethyl sulfoxide, and the mixture is stirred for 1/2 hour. Then 22.9 g of 1-methyl-3-trifluoromethyl-5-methylsulfonyl-1H-1,2,4-triazole are added, the reaction mixture is stirred for a further 2 hours and subsequently poured into 1 liter of ice water. The precipitated product is isolated by filtration, washed with water and dried. Yield: 19.6 g (76% of theory). Melting point: 111°14 112° C.
