Reaction Conditions

Temperature	100 °C

Reaction Steps

Iron (1.0 g) was added to a solution of 10 (500 mg, 2.6 mmol) in glacial acetic acid (10 mL). The reaction mixture was then heated at 100° C. for 20 minutes. The suspension was poured on aqueous NaOH 1M and extracted with ethyl acetate. After drying over Na2SO4, the solvent was then evaporated and 11 was isolated as a colorless solid (370 mg, 2.6 mmol, HPLC Rt=1.3 min, FIA ES+ 143.0).
