Procedure

To 10 ml of acetic acid were added 1.00 g of 4-(4-chlorobenzoyl)phthalic acid and 1.34 g of acetic anhydride, and the resultant mixture was refluxed under heating for 3.5 hours. After finishing the reaction, the acetic acid was evaporated in vacuo and the resultant residue was mixed with hexane. The precipitated solid was filtered, washed with hexane and dried to give 0.91 g of the titled compound.
