Reaction Steps
1-(4-Methoxyphenyl)-1H-indazole (30 mg, 0.134 mmol) was dissolved in dichloromethane (0.4 mL) and cooled to 40° C. Boron tribromide (0.4 mL, 1 M solution in dichloromethane, 0.4 mmol) was added, and the reaction was warmed to rt and stirred for 5 hours. Saturated sodium bicarbonate solution was added, and the mixture was extracted with dichloromethane. The extracts were dried over MgSO4 and concentrated to give the desired product. LC-MS (C13H10N2O calculated 210) m/z 211 (M+H).
