A solution of 2.00 g of 4-benzyl-3,5-dichloronitrobenzene in 2 ml of dichloromethane was added for a period of 15 minutes, and the reaction mixture was refluxed for 22 hours. The reaction mixture was poured into 25 ml of ice-water, and 30 ml of chloroform and 3 ml of conc. hydrochloric acid were added. The resulting mixture was stirred for 15 minutes at a room temperature, and the organic layer was separated, washed with water and saturated aqueous sodium bicarbonate solution, dried and concentrated to quantitatively give the above-identified compound as oil.
