Reaktionsschritte
This experimental procedure is an O-alkylation. A solution of bromomethane (48.90 g, 0.45 mol) is added dropwise to a stirred refluxing mixture of 6-Bromo-2-naphthol (40.00 g, 0.18 mol) and potassium carbonate (63.00 g, 0.46 mol) in acetone. The stirred mixture is heated under reflux for 24 hours (ie until glc analysis reveals a complete reaction). The potassium carbonate is filtered off, water is added to filtrate and the product is recrystallised from ethanol to give a yield of 43.92 g (97%).
