Participants

Reaction Steps

12.50 g of dimethyl 1,4,5,8-tetrakis(phenylmethoxy)-2,3-napthalene dicarboxylate prepared in Step 2A-c above was refluxed with 12.0 g of KOH in 24 mL of water, 300 mL of methanol and 100 mL of THF for 1 hour. The solvent was removed, and the residue acidified with 1N HCl. The solid was then collected by filtration and was refluxed in 55 mL of acetic anhydride for 30 minutes. After cooling to room temperature, a mixed solvent of 1:1 v/v diethyl ether and petroleum ether was added. The yellow crystalline solid was collected by filtration to yield 8.94 g of the title compound.
