実験手順

A 250 ml, 1-necked flask equipped with a magnetic stirrer and filled with nitrogen gas was charged with 15 ml of dry pyridine and 8.8 g (0.05 mole) of 2,6-dichloro-3-methylaniline. To the stirred solution was added 11.3 g (0.05 mole) of crude 5-acetylamino-3-chlorosulfonyl-1,2,4-triazole over 10-30 minutes. The resulting dark green mixture, which had a mild exotherm during the addition, was heated to 100°-105° C. with stirring for 3-4 hours. It was then dispersed between a mixture of methylene chloride and dilute aqueous sodium hydroxide and the organic layer was removed. Acidification of the aqueous phase and filtraton and drying of the precipitate that formed gave the title sulfonamide as a tan solid melting at 284° (dec.). The yield was 60 percent of theory. A sample of this compound which was recrystallized from a mixture of methanol and water was a pale ivory powder melting at 285°-285.5° C. (dec.) and had the following elemental analysis:
