Reaction Steps

A mixture of 1-(3,5-dinitrophenyl)pyrrole (1.52 g, 6.52 mmol) and SnCl2.2H2O (4.4 g, 19.57 mmol) in 30 mL of ethyl acetate was stirred over weekend at RT. The solvent was removed and the residue was taken in water. The aqueous layer was basified with 1 N NaOH to dissolve the tin salts, and the product was extracted into ethyl acetate. Chromatography (silica gel, hexane:ethyl acetate, 4:1) of the crude product provided 440 mg of 1-(3-amino-5-nitrophenyl)pyrrole.
