Versuchsvorschrift
2-(4-Methoxyphenyl)-4-(2-nitrophenyl)imidazole (10 g) is mixed with EtOH (80 ml) and 5% Pd-C (wet, 2 g). The mixture is shaken under hydrogen at 50 psi for 45 min. then filtered through Celite. The filtrate is evaporated under reduced pressure to yield 2-(4-methoxyphenyl)-4-(2-aminophenyl)imidazole (9.2 g) as a brown solid which is used in the next step without further purification.
