Reaction Steps

A mixture of 1-(3-nitrothiophen-2-yl)-1H-1,2,4-triazole (462 mg, 2.35 mmol), iron (1.31 g, 23.5 mmol) and ammonium chloride (163 mg, 3.06 mmol) in water (5 mL) was stirred at 100° C. for 18 h. The resulting suspension was filtered through a pad of diatomaceous earth and the filtrate was basified with aqueous NaOH. The aqueous solution was extracted with methylene chloride and the organic phase was separated, dried (Na2SO4), filtered and concentrated under vacuum to give 2-(1H-1,2,4-triazol-1-yl)thiophen-3-amine (314 mg, 1.89 mmol, 80%). Retention time (min)=0.454, method [1], MS (ESI) 167.0 (M+H).
