実験手順

The starting material is prepared as follows. The mixture of 6.2 g of 5-chlorohomophthalic acid and 70 ml of acetic anhydride is refluxed for 1/2 hour and evaporated. The residue is washed with chloroform, carbon tetrachloride and dryed to yield the 5-chlorohomophthalic anhydride melting at 170°-173°.
