Procedure
A solution of tert-butyl [(3R,4R,5S)-5-cyclopropyl-4-hydroxy-1-(3-nitro-6,7-dihydro-5H-cyclopenta[b]pyridin-4-yl)piperidin-3-yl]carbamate (0.113 g, 0.270 mmol) in anhydrous DCM (2.5 mL) was cooled to 0° C. and mCPBA (0.080 g, 0.33 mmol, 4×0.020 g) was added portion-wise. After 15 min., the reaction mixture was allowed to warm to ambient temperature and was stirred for 2 h. The reaction was quenched by the addition of a solution of Na2S2O3 (0.051 g, 0.32 mmol) in water (1 mL) followed by 4 M aq. NaOH (1 mL). The layers were separated and the organic fraction was concentrated and purified by flash column chromatography (20 g silica gel column, eluting with 0-30% MeOH/EtOAc) to afford the sub-title compound (0.050 g, 43%). LCMS (ESI) m/z calc. for C21H31N4O6 435.2 [M+H]+. found 435.0.
