Versuchsvorschrift

A suspension of urocanic acid (2.00 g, 14.5 mmol) in H2O (40 mL) was shaken at room temperature with a suspension of 10% Pd/C (200 mg, 0.19 mmol) under hydrogen atmosphere (30 psi) for 2 h. The catalyst was removed by filtration, and the filtrate was concentrated in vacuo to give a colourless solid (1.95 g, 96%). 1H NMR (D2O) δ 2.52 (t, 2H, J=7.2 Hz), 2.92 (t, 2H, J=7.2 Hz), 7.16 (s, 1H), 8.49 (s, 1H).
