反応手順
340 Milligrams of N-acetylamino-α-methylthiophenylacetic acid, 240 mg of isopropyl mercaptan, and 351 mg of potassium carbonate were added to 10 ml of a methanol-water mixture (9:1), and refluxed for 3 hours. Following a reduced pressure concentration of the reaction mixture to approximately 1 ml, 20 ml of water was added to the concentrate, which was then extracted with ethyl acetate. The organic phase was dried with Glauber's salt, and concentrated under reduced pressure. The residue was crystallized from an ether-n-hexane system, to provide 247 mg of α-acetylaminophenylacetic acid. The yield was 90%.
