Versuchsvorschrift

A mixture of benzyl 2-(4-hydroxypiperidin-1-yl)acetate (1.0 g, 4.0 mmol) and Pd/C (0.1 g) in methanol (20 mL) was hydrogenated for 1 h at ambient temperature. The Pd/C was filtered off and the filtrate was concentrated to dryness to afford 2-(4-hydroxypiperidin-1-yl)acetic acid (0.6 g, 94% yield).

Aufarbeitung

  1. filtrationThe Pd/C was filtered off
  2. concentrationthe filtrate was concentrated to dryness
