Procedure

A solution of Example 10A (1.69 g, 5.3 mmol) in DMF (20 mL) was treated with NIS (1.26 g, 5.6 mmol), stirred at room temperature for 3 hours, poured into water, and filtered. The filter cake was purified by flash column chromatography on silica gel with 15% ethyl acetate/hexanes to provide 1.64 g (70% yield) of the desired product. MS (ESI(+)) m/e 444.8 (M+H)+.
