Solvent was removed, and the residue was dissolved in ethyl acetate and washed with saturated sodium bicarbonate solution and brine (15 mL). The organic portions were pooled and dried over anhydrous sodium sulfate and the solvent was removed. The crude material was purified by reverse phase chromatography (Biotage) using ethyl acetate and hexanes as solvents to give 15 as white solid (0.035 g, 20%)

Tetrakis(triphenylphosphine) palladium(O) (0.363 g, 0.314 mmol) was then added and the system was purged with nitrogen, sealed, and heated to 70 C for 12h. The vessel was cooled to room temperature and diluted with EtOAc and water. The mixture was further diluted with brine and extracted three times with EtOAc. The combined organics were dried over MgS04, filtered, and concentrated to give the crude product. The crude material was purified by flash chromatography on silica using an ISCO machine (40 g S1O2 column, 40 mL/min, 0-40% EtOAc/hexanes over 15 minutes, tr = 8 minutes) to afford the title compound (300 mg, 24%).
