Benzoic acid, 2-chloro-5-(chlorosulfonyl)- → 2-Chloro-5-[(propan-2-yl)sulfamoyl]benzoic acid

Participants

Reaction Steps

5-(N-Isopropylsulfamoyl)-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-chlorosulfonyl-benzoic acid as the starting material, the product being obtained via 2-chloro-5-(N-isopropylsulfamoyl)-benzoic acid with a melting point of 170°-173° and 5-(N-isopropylsulfamoyl)-anthranilic acid with a melting point of 230°-232°; the product melts at 235°-237°.
