Vorschrift

3-(1H-imidazol-2-yl)pyridine (4.0 g, 0.0275M) and platinum oxide (0.5 g) in ethyl alcohol (50 ml) and 1NHCl (50 ml) was reduced at 45 psig of hydrogen for 4 hrs. The reaction mixture was filtered and the filtrate was stripped to dryness and crystallized from MeOH-EtOH to give 3-(1H-imidazol-2-yl)piperidine (4.5 g, 74% yield, mp 295° dec.).
