Reaction Steps

Nitro reduction, Method B: 5-[6-(1-Cyano-1-methylethyl)pyridin-3-yl]-2-nitrothiophene-3-carboxamide (95 mg, 0.29 mmol) and iron (III) chloride (2.33 mg, 0.014 mmol) were put in a vial. The vial was evacuated and backfilled with argon three times. Degassed methanol (4.1 mL) was added and the solution was heated to 65° C. for 10 minutes. Hydrazine hydrate (0.04 mL, 0.86 mmol) was then added and the reaction was stirred at 65° C. for 4 hours. After cooling to room temperature, the reaction mixture was filtered through Celite. The filtrate was concentrated in vacuo. The residue was taken up in water and ethyl acetate. The organic layer was separated, dried over magnesium sulfate, filtered, and concentrated under reduced pressure to afford the title compound as a solid.
