실험 절차

70% ethylamine in water (12.7 mL) and methanol (50 mL) are mixed. It is cooled to 0-5° C. 4-nitrobenzenesulfonyl chloride (10 g) is added portion-wise maintaining the temperature under 5° C. It is stirred for 15 minutes, maintaining the temperature, until the transformation is complete. Water (100 mL) is added. It is stirred for 30 minutes maintaining the temperature under 5° C. The reaction mixture is filtered, the isolated solid is washed with water and dried, obtaining 8.99 g of N-ethyl-4-nitrobenzene-sulfonamide.
