실험 절차

Iron powder (12 g), 42 mL of ethanol, 17 mL of distilled water, and 0.09 mL of 35% hydrochloric acid were mixed together, and the mixture was heated to reflux. Subsequently, (2-chloro-4-nitrophenyl)-(4′-chlorophenyl)methanone (8.9 g) dissolved in 12.8 mL of ethanol was added dropwise to the mixed solution, and the mixture was heated under reflux for one hr. This mixed solution was then cooled to room temperature, sodium bicarbonate water was then added thereto, and the mixture was filtered. The filtrate was concentrated under the reduced pressure, and ethyl acetate and brine were added to the residue, followed by separation. The ethyl acetate layer was washed with brine and was then concentrated under the reduced pressure to give 7.56 g of (4-amino-2-chlorophenyl)-(4′-chlorophenyl)methanone (yield 95%).
