Procedure

15.26 g of 50% sodium hydride in oil is added, at 0° C., to a solution under inert gas of 50 g of parabromophenol in 320 ml of dimethylformamide, followed by agitation for 30 minutes at 0° C., then 37.7 ml of benzyl bromide is added. Agitation is carried out for 2 hours 30 minutes while allowing the temperature to return to 20° C., then the reaction mixture is poured into ice-cooled water, the precipitate is filtered and dried. 73.35 g of expected product is obtained.
