Ethanol → HCID 69521797, compound

Participants

Reaction Steps

A mixture of 6-methyl-3-[[(4-nitrophenyl)thio]methyl]imidazo[1,2-a]pyridine (3.0 g), reduced iron (2.80 g) and calcium chloride (0.56 g) in 15% water-containing ethanol (150 ml) was heated to reflux for 20 hours. The insolubles were removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was extracted with ethyl acetate, washed with saturated brine, and dried over magnesium sulfate. The solvent was concentrated under reduced pressure, and the obtained residue was separated and purified by column chromatography (ethyl acetate:hexane 1:1→2:1), to give 4-[[(6-methylimidazo[1,2-a]pyridin-3-yl)methyl]thio]aniline (2.38 g) as pale yellow crystals.
