Reaction Conditions:

with potassium tert-butylate in N-methyl-acetamide;ethanol;

Steps:

17 2,7-Dibenzyloxy naphthalene

EXAMPLE 17 2,7-Dibenzyloxy naphthalene To a stirred solution of 2,7-dihydroxynaphthalene (50 mmol, 8.0 g) and benzylchloride (0.11 mol, 13.9 g) in dimethylformamide (200 ml), potassium tert-butylate (0.11 mol, 13.4 g) was added in 3 hours (under nitrogen, 30° C.). After stirring for 5 hours, CH₂ Cl₂ (300 ml) was added and the mixture extracted with water (3*300 ml), dried over MgSO₄ and the solvent evaporated. Recrystallization of the residue from ethanol gave 5.5 g of the ether (32% yield, mp 161° C.). ¹ H-NMR (CDCl₃, ppm^j(Hz)): 5.18(4H); 7.12^m (4H); 7.32-7.54^m (10H); 7.70^8.5 (2H).
