Participants

Reaction Steps

A mixture of 10.00 g of dimethyl 1,4-dihydroxy-5,8-bis(phenylmethoxyl)-2,3-naphthalene dicarboxylate prepared in Step 2A-b above, 12.00 g of potassium carbonate and 8.0 mL of benzyl bromide in 100 mL of dimethyl formamide and 200 mL of acetone was stirred at room temperature for 2 days. The reaction was filtered. The filtrate was then concentrated and the solid was washed with mixed solvent of ethyl acetate and petroleum ether to give 12.50 g of the title compound as a yellow solid.
