Add slowly a solution of N-iodosuccinimide (1.035 g, 4.6 mmol) in DCM (100 mL) over a period of 3 h. Stir the reaction mixture overnight and gradually warm to RT. Quench the reaction with saturated aqueous sodium bicarbonate, separate the organic layer, wash the organic layer with 0.1 N HCl, brine, dry (sodium sulfate) concentrate and purify (silica gel chromatography, eluting with 5:95 to 10:90 EtOAc:hexanes) to give the title compound as a white solid (1.0 g, 65%).
