Reaction Steps

A solution of the product of EXAMPLE 1A (4.52 g, 15.34 mmol) in tetrahydrofuran (75 mL) was treated with palladium tetrakis(triphenylphosphine) (0.887 g, 0767 mmol) and 2,6-dichlorobenzyl zinc chloride (46 mL, 0.5M in tetrahydrofuran). The mixture was heated at 85° C. for 1 hour. After cooling to ambient temperature, the mixture was diluted with water and extracted with ethyl acetate. The organics were washed with brine, dried (sodium sulfate), filtered and concentrated under reduced pressure. Purification by silica gel chromatography (0-100% ethyl acetate in hexanes) provided the title compound. MS (LC-MS) m/z 342 (M+H)+.
