3-Hydroxybenzyl alcohol → 3-(Chloromethyl)phenol

3-Hydroxybenzylalcohol (5 g, 40 mmol) and triethylamine (5.2 ml, 60 mmol) were dissolved in benzene (250 ml), and thionylchloride (5.2 ml) dissolved in benzene (50 ml) was added thereto at 0° C. The brownish reacting solution was stirred at room temperature for 6 hours. When the reaction was completed, the solution was washed with brine, and the water layer was extracted with methylene chloride. The organic extract was dried over anhydrous magnesium sulfate and concentrated under a reduced pressure to obtain the title compound (5.7 g, 99%).
