Reaction Steps

A suspension of 2-((3aR,4S,6R,6aS)-6-(6-chloro-5-nitro-2-(propylthio)pyrimidin-4-ylamino)-2,2-dimethyl-tetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yloxy)ethanol (800 mg, 1.78 mmol, 1.00 equiv.), iron powder (800 mg, 14.29 mmol, 8.00 equiv.), acetic acid (860 mg, 14.33 mmol, 8.00 equiv.) and water/ethanol (10 mL) was stirred at about 60° C. for about 20 minutes in an oil bath. After the solids were removed by filtration, the resulting filtrate was extracted with dichloromethane (3×10 mL). The organic layers were combined, dried over anhydrous sodium sulfate, and concentrated in vacuo to give the title product as a yellow oil (780 mg; yield=93%). MS: m/z=419 (MH)+.
