Versuchsvorschrift
A mixture of 1-(3-nitrobenzyl)imidazole (0.5 g, 0.0025 mol) and palladium on charcoal (0.05 g, 10%) in dry ethanol (20 ml) was stirred under an atmosphere of hydrogen for 0.25 h. The reaction mixture was then filtered through Hyflo-supercel, and the ethanol was evaporated under reduced pressure to give a colourless oil. The oil was distilled to yield 1-(3-aminobenzyl)imidazole, b.p. 160°/0.01 mm Hg, which solidified on cooling. Recrystallisation of the solid from toluene gave the product as a white solid, m.p. 75°-76°.
