실험 절차

A mixture of 4-{(3S)-3-[(tert-butoxycarbonyl)amino]piperidin-1-yl}-3-nitro-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (64 mg, 0.15 mmol), AcOH (0.90 mL), water (0.10 mL) and iron powder (149 mg, 2.66 mmol) was stirred at room temperature for 20 min. The mixture was diluted with EtOAc and filtered through a short silica gel plug. The filtrate was concentrated under reduced pressure, diluted with EtOAc and washed with aq. Na2CO3. The organic layer was dried, filtered and concentrated under reduced pressure to give the sub-title compound (66 mg) as a yellowish solid, which was used without further purification. LCMS calc. for C20H31N4O4 (M+H)+: m/z=391.2. Found: 391.1.
