反応手順
To a solution of 78 (170 mg, 0.93 mmol) in AcOH (5 mL), EtOH (5 mL) and H2O (2.5 mL) was added iron powder (311 mg, ˜325 mesh, 5.57 mmol) portion wise. The mixture was then heated at 90° C. under N2 overnight. After cooling to room temperature, the mixture was poured onto ice, basified using solid Na2CO3 and extracted with EtOAc (3×). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated in vacuo to yield 79 as a pale yellow solid (139 mg, 98%). MS (APCI): m/z 154 (100%, [M+H]+) which was used in the next step without further purification.
