89% | With potassium carbonate;tetrabutylammomium bromide; In acetonitrile; for 2.75h;Heating / reflux; | Preparation of 7-Bromo-1-methoxynaphthalene. [CHEMMOL-00140] [0466] A slurry of <strong>[91270-69-8]7-bromo-1-naphthol</strong> (8.89 g, 39.9 mmol), potassium carbonate (8.26 g, 59.8 mmol), dimethyl sulfate (5.66 mL, 59.8 mmol) and tetrabutylammonium bromide (0.085 g, 0.264 mmol) in acetonitrile (160 mL) was heated at reflux for 2 h 45 min. The reaction was cooled to room temperature, and water was added (200 mL). The mixture was then extracted (1.x.100, 1.x.40 mL) with CH2Cl2. The combined organic layers were washed (1.x.40 mL) with saturated aqueous NaHCO3 solution, dried over MgSO4, and concentrated. The residue was purified by medium pressure chromatography (100percent hexanes) to give the intermediate title compound as a yellow oil (8.42 g, 89percent). FDMS m/e=236 M+. |
