Procedure

A mixture of 45.8 g of 3-allyloxy-phthalic acid in 200 ml of toluene and 25.5 ml of acetic anhydride is heated to the reflux temperature for 3 hours and then evaporated under reduced pressure. The residue is crystallised from diethyl ether and gives 3-allyloxy-phthalic anhydride; melting point 115°-117°.
