Reaction Steps
Tin chloride dihydrate (4.0 g) was added to 5-nitro-3-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridine (0.58 g) in ethyl acetate (50 mL). The resulting solution was refluxed for 3 hours. The cooled solution was treated with dilute aqueous sodium bicarbonate. The resulting slurry was filtered through celite, and the filter cake was washed with ethyl acetate. The layers were separated. The organic layer was washed with brine, dried over magnesium sulfate, filtered, and evaporated to provide 5-amino-3-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridine (320 mg, 63%) as a solid.
