To a stirred solution of 3',5'-dichloro-N-methylbenzanilide (2.317 g) in tetrahydrofuran was added lithium aluminum hydride (380 mg) in an ice-bath and the resulting suspension was stirred at the same temperature for one hour. The reaction mixture was quenched with saturated ammonium chloride and filtered through celite pad. The inorganic material on the celite was washed with ethyl acetate. Methanol was added to the filtrate and stirred at ambient temperature for half an hour. The organic layer was washed with water, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was purified by flash chromatography eluting with ethyl acetate-n-hexane (1:9, V/V) to afford 3,5-dichloro-N-methylaniline (1.38 g) as a colorless oil.
