Reaction Steps
In a manner analogous to that described in Example 1, the reaction of 5-(N-isopropylsulfamoyl)-isatoic anhydride with 1-methylpiperazine yields 5-(N-isopropylsulfamoyl)-anthranilic acid (4-methyl)-piperazide with a melting point of 118°-122° (from methylene chloride/diethyl ether; melting point of the methanesulfonate: 232°-234°).
