Procedure

Aluminium chloride (9.5 g) was added to a solution of 2,3-dimethoxynaphthalene (10 g) and succinic anhydride 7.1 g in methylene chloride (140 ml). The mixture was stirred at room temperature overnight and then treated with water and filtered. The resulting solid was taken into 1 M sodium hydroxide, washed once with methylene chloride, acidified and filtered. Yield: 8.3 g, melting point 215-229° C.
