6966-10-5

94416-66-7

3,4-Dimethylbenzyl alcohol (1.00 g, 7.34 mmol) was dissolved in dichloromethane (10 mL) at 0 °C and tribromophosphine (1.2 g, 4.41 mmol) was added slowly, keeping the reaction mixture stirred for 3 h at this temperature. Upon completion of the reaction, the reaction was quenched with deionized water (20 mL) followed by extraction with dichloromethane (20 mL x 3). The organic phases were combined, washed with saturated saline (40 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford 3,4-dimethylbenzyl bromide as a colorless oil (1.2 g, yield: 82%). The product was characterized by 1H NMR (400 MHz, CDCl3) with chemical shifts of δ 7.17 (s, 1H), 7.15-7.09 (m, 2H), 4.47 (s, 2H), 2.25 (s, 6H) ppm.
