Acetic Acid → 4-(4-cyano-1H-imidazol-1-yl)-3-methoxyaniline

Participants

Reaction Steps

To a solution of 1-(2-methoxy-4-nitrophenyl)-1H-imidazole-4-carbonitrile (689 mg, 2.82 mmol) in EtOH (Ratio: 2, Volume: 15 mL) was added Acetic Acid (Ratio: 1.000, Volume: 7.50 mL) and Iron (630 mg, 11.29 mmol). The resulting mixture was brought to 100° C. and stirred for 2 h. The reaction was then diluted with water and brought to pH 8 by the addition of 1 N aqueous sodium hydroxide. This mixture was extracted with EtOAc (3×5 mL). The combined extracts were washed with water (5 mL), brine (5 mL), dried over MgSO4, filtered and concentrated in vacuo. LC-MS (M+H)+=215.0.
