Reaktionsschritte
A solution of dimethyl 2,6-naphthalenedicarboxylate (39.6 g, 162 mmol) in dioxane (1.2 L) was heated to 70-80° C., slowly treated with a solution of KOH (9.1 g, 162 mmol) in methanol (162 mL), heated to 70° C., stirred for 30 minutes, cooled to room temperature, and filtered. The solid was washed sequentially with dioxane and diethyl ether, dissolved in water, adjusted to pH<7 with 1M HCl, and filtered. The solid was washed with water and dried to provide the desired product.
