Participants

Reaction Steps

5-[N-(2-Butyl)-sulfamoyl]-isatoic anhydride, which is to be used as the starting material, can be obtained, for example, in a manner analogous to that described in Example 1, using 2-chloro-5-chlorosulfonylbenzoic acid as the starting material, the product being obtained via 5-[N-(2-butyl)-sulfamoyl]-2-chloro-benzoic acid with a melting point of 118°-123° and 5-[N-(2-butyl)-sulfamoyl]-anthranilic acid with a melting point of 187°-188°. It melts at 228°-229°.
