Versuchsvorschrift

N-tert-butyl-3-((4-(3-fluoro-4-nitrobenzoyl)-2-(fluoromethyl)piperazin-1-yl)methyl)benzamide (435 mg, 0.92 mmol), iron powder (558 mg, 10 mmol) and 1M hydrochloric acid (1.5 mL, 1.5 mmol) were stirred in isopropyl alcohol (30 mL) for 1 hour. The reaction was concentrated under reduced pressure and the residue partitioned between dichloromethane and water. The organic layer was separated, dried (sodium sulfate) and concentrated under reduced pressure. The crude product was purified using silica chromatography to give the title compound (150 mg). MS (ESI) m/z 445.6 [M+H]+
