Versuchsvorschrift
To a solution of tert-butyl [(3S,5S)-5-(2,3-difluorophenyl)-2-thioxopiperidin-3-yl]carbamate (100 mg, 0.29 mmol) in methanol (2.9 mL) was added hydrazine hydrate (55%, 780 μL, 8.76 mmol). The mixture was stirred 40 min, and then concentrated. Water was added, and the mixture was extracted with ethyl acetate (×3). The combined organic extracts were washed with brine, dried over magnesium sulfate, filtered and concentrated to give the crude title compound. MS 341.2 (M+1).
