Reaction Steps

To a stirred mixture of N-(5-Bromo-2-iodo-benzyl)-N-(3-vinyl-pyridin-2-yl)-acetamide E (60.0 mg, 0.13 mmol) and triethyl amine (55.0 μL, 0.39 mmol) in anhydrous DMF (1.4 mL) under argon was added Palladium dichloride (4.60 mg, 26 μmol). This mixture was heated at 65° C. for 1 h, cooled and diluted with saturated NaHCO3 solution (20 mL). The mixture was extracted with EtOAc (4×30 mL). The combined EtOAc extracts were washed with water (3×10 mL), brine (1×10 mL), dried (MgSO4), filtered and concentrated in vacuo. This was purified by a ISCO auto CombiFlash with a RediSep 4 g column, eluted with CH2Cl2-EtOAc, detected at 254 nM to give 33 mg of 78F in 77% yield. HPLC Rt=3.04 min (YMC S5 ODS column 4.6×50 mm, 10-90% aqueous methanol over 4 minutes containing 0.2% phosphoric acid, 4 mL/min, monitoring at 220 nm) LC/MS: M+H=329.
