Ammonium Chloride → 2-Methoxy-1-phenylnaphthalene

참여 물질

반응 단계

In a flask charged with 1-bromo-2-methoxynaphthalene (20.0 g, 84.4 mmol), phenylboronic acid (11.3 g, 92.8 mmol), palladium acetate (0.10 g, 0.46 mmol), triphenylphosphine (0.85 g, 2.78 mmol) and potassium phosphate (40.9 g, 177.9 mmol), mixture of water (60 mL) and dimethoxyethane (120 mL) was added, and the resultant mixture was heated under reflux for 6 hours. After cooling to ambient temperature, aqueous ammonium chloride (150 mL) and diethyl ether (200 mL) were charged thereto. The organic layer was isolated, and the residue was extracted with diethyl ether. Combined organic layer was dried over magnesium sulfate, and evaporated to remove the volatiles. Purification via silica gel column chromatography (eluent: hexane) gave 2-methoxy-1-phenylnaphthalene (13.0 g, yield: 66%) as colorless liquid.
