Procedure

A solution of the product of Example 255B (0.660 g, 1.52 mmol), iron powder (0.339 g, 6.07 mmol) and ammonium chloride (0.099 g, 1.82 mmol), tetrahydrofuran (18 mL), and water (6 mL) solution was heated to reflux for 3 hours. The resultant mixture was diluted with methanol (50 mL) and filtered through a pad of celite. The filtrate was diluted with water (50 mL) and extracted with dichloromethane (2×100 mL). The combined extracts were dried over magnesium sulfate, filtered and concentrated under vacuum to provide the title compound (0.60 g, 97%).
