反応手順

Two (2.0) cc of Raney nickel (WII) was suspended in 15 ml of acetone, and refluxed for 7 minutes. Cooling the suspension to room temperature, 315 mg of α-acetylamino-α-tolylthiophenylacetic acid was added, followed by 5.5 hours' stirring at room temperature. The insoluble matter was separated by filtration, and washed with ethanol. The filtrate and washing were combined and concentrated under reduced pressure. The residue was crystallized from an ether-n-hexane system. Thus 141 mg of α-acetylaminophenylacetic acid was obtained. The yield was 73%.
