Reaction Steps

A solution of the product from Example 217C (0.1 g, 0.257 mmol), iron powder (0.058 g, 1.03 mmol) and ammonium chloride (0.017 g, 0.310 mmol) in a methanol (5 mL), tetrahydrofuran (5 mL), and water (2 mL) solution was heated to reflux for 1.5 hours. The resultant mixture was diluted with methanol (50 mL) and filtered through a pad of celite. The filtrate was concentrated under vacuum to a volume of 10 mL, the solution diluted with water (50 mL) and extracted with ethyl acetate (2×50 mL). The combined extracts were washed with 10% sodium chloride then dried over magnesium sulfate, filtered and concentrated under vacuum to provide the title compound (0.04 g, 43%).
