Procedure

Under a nitrogen atomersphere, 32 (88 mg, 0.21 mmol) was dissolved in dichloromethane (6 mL) followed by the addition of BBr3 (0.2 mL, 2.1 mmol). The reaction was stirred overnight at room temperature and then quenched with ice. The mixture was partitioned between EtOAc and water and the organic layer was separated, washed with brine, and dried over Na2SO4. The solids were filtered off and the filtrate was concentrated in a rotavap to give 70 mg of the title compound as a brownish solid ESI [M+H+]=402.24.
