反应详情

A mixture of 32 g of 4-bromo-2-isopropylphenol, 25.7 g of benzyl bromide, 23 g of potassium carbonate and 300 ml of N,N-dimethylformamide was stirred at room temperature for 24 hours. The reaction solution was poured into ice-water, acidified by adding 10% hydrochloric acid and then extracted with 500 ml of diethyl ether. There, the ether layer was washed with a saturated saline solution, dried over anhydrous magnesium sulfate and concentrated. The residue was subjected to silica gel column chromatography to give 30 g of 4-bromo-2-isopropylphenyl benzyl ether (yield, 65%).
