Participants

Reaction Conditions

Reaction Steps

In a manner similar to that described in Example 3, 8.8 g (0.05 mole) of 2,6-dichloro-3-methylaniline, 9.6 g (0.05 mole) of 5-amino-3-chlorosulfonyl -1,2,4-triazole and 25 ml of dry acetonitrile were stirred at about 65° C. for a total of 5 days. The reaction product was recovered as in Example 3 to obtain 10.8 g of the title compound as white solid, m.p. 240°-241° C. (dec.). This assayed by HPLC to be about 98 percent pure. The methylene chloride washes were concentrated to obtain 2.7 g of solid which was over 80 percent purity unreacted 2,6-dichloro-3-methylaniline. The yield of the desired sulfonamide was therefore 88 percent based on unrecovered aniline.
