Reaction Conditions:

with boron tribromide in dichloromethane at -60 - 0;

Steps:

3.2 Step 2 3-(2H3)methylphenol as brown oil:

To a solution of 1-methoxy-3-(2H3)methylbenzene (9 g, 71.89 mmol, 1.00 equiv) in dichloromethane (10 mL) was added BBr3 (144 mL, 2.00 equiv) at -60 °C. The resulting solution was stirred for 2 h at 0 °C. The reaction was then quenched by the addition of water/ice. The resulting solution was extracted with dichloromethane (3 x 50 mL). The organic layers were treated with sodium hydroxide solution (10%). Then the aqueous layers were acidified with hydrogen chloride (1 M), extracted with dichloromethane (3 x 50 mL), dried over anhydrous sodium sulfate and concentrated under vacuum to afford 6 g (75%) of 3-(2H3)methylphenol as brown oil.
