Reaction Steps

To a solution of 11B (0.16 g, 0.79 mmol) in EtOAc (2 mL) was added iron powder (0.1 g), followed by 10% aqueous AcOH (2 mL). The mixture was stirred at 60° C. for 2 h, then allowed to cool to rt and partitioned between saturated NaHCO3 and EtOAc. The separated EtOAc layer was concentrated under reduced pressure to give the title compound (0.14 g) as a solid.
