Procedure
To a cold (0° C.) suspension of AlCl3 (1.67 g, 12.51 mmol, 1 equiv) in nitromethane (20 mL) is added a solution of 4-bromo-2-tert-butyl-1-(3-hydroxy-3-methylbutoxy)benzene (3.94 g, 12.51 mmol) in nitromethane (5 mL). The resulting red solution is stirred at 0° C. After 1 h, the reaction mixture is quenched by slow addition of water, diluted with hexanes, and washed with water and brine. The aqueous layers are extracted with hexanes; the combined organic layers are dried (MgSO4), filtered and concentrated. The residue is purified by flash column chromatography on silica (hexanes) to give the title compound (2.87 g, 77%) as a solid which is recrystallized using hexanes to give white crystals.
