Procedure

To a stirred solution of 3-(4-propyl-2-methoxyphenoxy)-2-nitropyridine (1.1 g, 3.8 mmol) in methanol (15 ml) was added anhydrous Ferric chloride (55 mg, 5% by wt) and activated charcoal (55 mg, 5% by wt). The resulting mixture was heated to reflux and hydrazine hydrate (570 mg, 11.45 mmol) was added dropwise. The reaction was allowed to stir under reflux condition overnight, then filtered through celite. The filtrate was concentrated under reduced pressure, taken in ethyl acetate (150 ml). The organic layer was washed with water followed by brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was passed through silica column (eluant ethylacetate/pet ether 1:3 to get 900 mg (91.3%) of title compound as a pale yellow solid.
