실험 절차

20.7 g of 5-aminobenzotriazole dihydrochloride and 30 g of sodium hydrogen carbonate were dissolved in 300 ml of water, and 10 g of acryl chloride was added dropwise at a temperature of lower than 10° C. over 20 minutes. After being stirred for 1 hour, the formed white precipitate was filtered off. Yield: 13.8 g. It was dissolved in 100 ml of DMF, and 500 ml of hot water at about 70° C. was added. It was immediately filtered under atmospheric pressure. The filtrate was allowed to cool, and the separated crystals were filtered out, washed with water and dried to obtain 11 g of the desired product which melted at 248°-253° C. The structure was confirmed by IR, NMR and elementary analysis.
