Procedure

Proceeding in a similar fashion to the one described in part A of Example 17, 28.6 g (0.01 mole) of tetrachlorophthalic anhydride, 16.2 g (0.2 mole) of N-methylpyrrole and 40 g (0.3 mole) of aluminum chloride were interacted in 50 ml of dry chlorobenzene to obtain 2-[(1-methyl-2-pyrrolyl)carbonyl]-3,4,5,6-tetrachlorobenzoic acid (Formula IX: Ro =R1 =R2 =R3 =Cl; R7 =CH3) having a melting point of 203°-205° C.
