Reaction Steps

The crude product from Example 72C and triphenylphosphine (0.730 g, 2.78 mmoles) in anhydrous DMF (5 mL) at 0° C. were treated with N-bromosuccinimide (0.396 g, 2.24 mmoles). Reaction mixed at 0° C. for 30 minutes. Reaction diluted with ethyl acetate, washed with H2O (2×), brine, dried (Na2SO4), filtered, and the filtrate concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, 30% ethyl acetate:hexanes) to provide the title compound (0.214 g, 63%). MS (ESI+) m/z 609 (M+H)+.
