Procedure

A mixture of the compound obtained in (2) described above (2.2 g), reduced iron (2.0 g), ammonium chloride (780 mg), ethanol (40 mL) and water (10 mL) was heated under reflux for an hour. After cooling to room temperature, the reaction solution was filtered through Celite and the filtrate was concentrated in vacuo. Dichloromethane (50 mL) and water (50 mL) were added to the residue, and the aqueous layer was separated and extracted with dichloromethane (40 mL×2). The combined organic layer was washed with brine, dried over sodium sulfate and concentrated in vacuo to give the titled compound (2.0 g) as a yellow powder, which was used in the next step without further purification.
