Procedure

(IM15) (3.596 g, 23.11 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]-dichloropalladium(II) (1.694 g, 2.315 mmol) in THF (100 mL) under N2. A 1 M solution of diethyl zinc in hexane (35 mL, 35 mmol) was added drop wise to this mixture followed by N,N-dimethylaminoethanol (0.50 mL, 5.0 mmol). The mixture was heated to reflux for 30 minutes. The mixture was cooled to room temperature and then quenched by the addition of saturated aqueous NH4Cl solution (100 mL). The mixture was filtered through a plug of celite. The aqueous layer was extracted with EtOAc (3×100 mL). The combined organic layers were washed with water, brine and then dried over Mg2SO4. Flash Chromatography (120 g silica, 0-40% EtOAc in heptanes) gave the title compound as a yellow oil (0.699 g, 20%) sufficiently pure for the next step.
