Participants

Reaction Steps

5-[N-(2-Methylpropyl)-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 2-chloro-5-[N-(2-methylpropyl)-sulfamoyl]-benzoic acid with a melting point of 163°-166° and 5-[N-(2-methylpropyl)-sulfamoyl]-anthranilic acid with a melting point of 203°-205°; the product melts at 270°-273°.
