Reaktionsschritte

To a mixture of 26 g of 4-bromo-2-ethyl-6-methylphenol, 24.8 g of benzyl bromide and 200 ml of N,N-dimethylformamide was added 21.7 g of potassium carbonate with stirring at room temperature. After stirring at room temperature for 24 hours, the reaction mixture was poured into ice water and extracted twice with 500 ml of diethyl ether. The diethyl ether layers were combined, washed with water, dried over anhydrous magnesium sulfate and then concentrated to give a crude product. The crude product was subjected to silica gel chromatography, which afforded 35.6 g of 4-bromo-2-ethyl-6-methyl-1-benzyloxybenzene (yield, 97%).
