Procedure

6-chloro-2-(5-fluoro-2-nitrophenylamino)-9-(trans-4-hydroxycyclohexyl)-7H-purin-8(9H)-one (13.5 mg, 0.03 mmol) was dissolved in CH3COOH:H2O:EtOH (1 mL:2.5 mL:5 mL) and iron powder (18 mg, 0.32 mmol, 10 equiv.) was added. The reaction mixture was then heated to 90° C. with continuous stirring for 15 minutes. Completion of the reaction was monitored by analytical HPLC and MS analysis. The reaction mixture was cooled to room temperature. Saturated NH4OH was added to the cooled solution slowly, with stirring, until pH was 11-12. It was then diluted with EtOAc (15 mL). The organic layer was separated, and the aqueous layer extracted with EtOAc (3×15 mL), the combined organic layers were washed with brine (1×15 mL), dried over MgSO4 and concentrated to give a white solid (12 mg, 96% yield), which was used without purification in the next step. MS (EI) m/z 393 (MH)+.
