A solution of 24.5 g of 2-(1-naphthylmethylene)succinic acid in 260 ml of acetic anhydride was heated at 60° C. for 1 hour, and the reaction mixture was evaporated under reduced pressure. A mixture of benzene and hexane (1:1) was added to the residue, and the precipitated crystals were collected by filtration to obtain 16.0 g of 2-(1-naphthylmethyl)succinic anhydride as orange yellow crystals.
