Reaction Steps

To the solution of 1,2-dimethoxynaphthalene (3.83 g, 20.3 mmol) in THF (100 mL) was added dropwise at 0° C. a solution of NBS (3.62 g, 20.3 mmol) in THF (50 mL). After stirring at 0° C. for 0.5 h, the solvent was removed in vacuo and CCl4 was added. The mixture was filtered and the filtrate was concentrated. Column chromatography yielded the title compound as a yellow oil (3.72 g, 68%). 1H NMR (CDCl3) δ 8.1 (m, 2H), 7.60 (s, 1H), 7.49 (m, 2H), 3.99 (s, 3H) 3.98 (s, 3H); MS m/z 267 (M−H).
