Versuchsvorschrift

1-(4-nitrophenyl)-1H-imidazole (4.4 g; 23.5 mmoles) is put in solution in anhydrous methanol (140 ml) and palladium on carbon (0.44 g) is added to the medium. The reaction medium is placed under hydrogen for 4 hours. The catalyst is filtered off and the solvent is evapored to dryness. The expected product is obtained in a virtually pure state with a yield of 89% (3.3 g).
