실험 절차

A mixture of dimethyl 4-hydroxyphthalate (2.1 g; 0.01 mole), 1-bromo-3-phenoxypropane (2.15 g; 0.01 mole) and anhydrous potassium carbonate (1.52 g; 0.015 mole) in dry butanone (30 ml) was stirred at reflux overnight and the cooled mixture filtered. Evaporation in vacuo afforded the title compound in quantitative yield. νmax (film) 1730, 1605 cm-1 ; τ(CDCl3) 7.77 (2H, quintet, J 6.5 Hz); 6.16 (3H,s); 6.11 (3H, s); 5.86 (2H, t, J 6.5 Hz); 5.78 (2H, t, J 6.7 Hz); 3.20-2.55 (7H, m); 2.19 (1H, d, J 8.5 Hz); (Found; C, 65.98; H, 5.89; C19H20O6 requires; C, 66.27; H, 5.85%).
