Participants

Reaction Steps

To a solution of 3-(4-methoxyphenyl)-7-phenyl-1-propyl-1H-indazole (0.375 g, 1.09 mmol) in CH2Cl2 (15 mL) was added BBr3 (0.207 mL, 2.19 mmol) at −78° C. The solution was stirred for 15 minutes and allowed to stand overnight in the refrigerator. The reaction was quenched with NH4OH (20 mL) and extracted with CH2Cl2. The organic layer was washed with water and dried (MgSO4). The reaction was purified by flash chromatography (5/1 hexane/ethyl acetate) to give the title compound as a white solid (0.147 g, 0.45 mmol, 41%).
