Procedure

Proceeding in a manner similar to that described in part A of Example 16, 14.8 g (0.1 mole) of phthalic anhydride, 16.2 g (0.2 mole) of N-methylpyrrole and 39.0 g (0.3 mole) of aluminum chloride were interacted in 50 ml of chlorobenzene to obtain 2-[(1-methyl-2-pyrrolyl)carbonyl]benzoic acid (Formula IX: Ro =R1 =R2 =R3 =H; R7 =CH3) melting at 165°-167° C. A significant infrared absorption maximum appeared at 1710 cm-1 (C=O; s).
