Versuchsvorschrift
To 3-(1-imidazolyl)nitrobenzene (51.6 g, 0.27 mol) in acetic acid (500 ml) is added palladium catalyst (5 g 5% Pd on activated carbon) and the mixture is hydrogenated under pressure (Pstart : 4 bar) until the hydrogen uptake has ceased. The mixture is filtered through celite and the filtrate is evaporated to dryness to leave 2d as a light-brown oil. Yield: 40.4 g (93%).
