실험 절차
6-Bromo-2-methoxynaphthalene (5.9 g, 24.81 mmol, 1 eq) and NBS (4.41, 24.81 mmol, 1 eq) are boiled in 50 ml of THF under reflux for 2 h. After washing with 1 N HCl, the organic phase is dried over magnesium sulfate, filtered and concentrated in vacuum on a rotary evaporator. The compound is obtained in quantitative yield (7.8 g).
