Conditions

Temperature
60 °C

Procedure

100 ml of acetic anhydride were added to 10 g (35 mmole) of 2-(1-naphthylidene)adipic acid (prepared as described above) and the mixture was stirred at 60° C. for 1 hour. At the end of this time, the solvent was removed by distillation under reduced pressure, and the resulting residue was triturated with a 1: 1 by volume mixture of benzene and hexane. The solvent was decantated to afford 8.8 g of 2-(1-naphthylidene)adipic anhydride as an oily material.
