Procedure

Synthesized using compound 65b (982 mg, 5.77 mmol), NBS (1.13 g, 6.35 mmol) and DBPO (70 mg, 0.29 mmol) in carbon tetrachloride according to Method A. Crude product was purified by flash chromatography on silica-gel using hexane/ethyl acetate (4:1) as eluent. Product was used directly in the next step without further characterization. Orange solid. Yield: 53 mg, 4%. (ESI): m/z=250.67 [M+H]+.
