Participants

Reaction Steps

To 1-[2-[(4-nitrophenyl)sulfanyl]ethyl]imidazole (0.60 g) was added 85% ethanol solution (18 ml), and to this solution was added calcium chloride (0.13 g) and reduced iron (0.67 g), and the mixture was heated to reflux for 3 hours. After cooling to room temperature, the mixture was filtered with Celite, and washed with ethyl acetate. The solvent was removed under reduced pressure, and the obtained residue was dissolved in ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give 4-[[2-(imidazol-1-yl)ethyl]sulfanyl]phenylamine (0.48 g).
