Reaction Steps

To a suspension of (±)-methyl 1-benzoyl-4-piperidinecarboxylate (502 mg, 2.03 mmol) in MeOH (10 mL) was added hydrazine hydrate (1.6 mL). After stirring for 24 h at rt, the reaction mixture and water (40 mL) was added. After washing with Et2O (2×20 mL), the aqueous layer was evaporated off under vacuo. The title compound was obtained as an amorphous beige solid (469 mg, 93%) in a 91.0% purity by HPLC (MaxPlot detection between 230 and 400 nm).
