Reaction Steps
A mixture of iodide 37 (2.00 g, 4.89 mmol), furan-3-boronic acid (820 mg, 7.33 mmol), PdCl2(PPh3)2 (343 mg, 0.49 mmol), LiCl (622 mg, 14.7 mmol), 1.0 M aqueous Na2CO3 (12.2 mL, 12.2 mmol), EtOH (23 mL) and toluene (23 mL) were refluxed for 50 min. After cooling the layers were separated, brine was added to the aqueous layer and extracted with ethyl acetate (3×50 mL). The combined organic extracts were dried (MgSO4) and concentrated. The resulting solid was purified by silicagel chromatography using 30% ethyl acetate in hexane (gradient elution) to give 38 as an orange solid (1.23 g, 72%);
