Diclofenac, a potent antiinflammatory agent, was prepared by acid-catalyzed cyclization of N-(2, 6-dichlorophenyl)-α-(methylsulfinyl) acetanilide or of α-chloro-N-(2, 6-dichlorophenyl)-α-(methylthio) acetanilide followed by desulfurization and hydrolysis of the resultant 1-(2, 6-dichlorophenyl)-3-(methylthio) oxindole.
双氯芬酸是一种强效的抗炎药物,通过酸催化的环化反应制备自N-(2, 6-二氯苯基)-α-(甲基亚磺酰基)乙酰苯胺或α-氯-N-(2, 6-二氯苯基)-α-(甲基硫基)乙酰苯胺,随后对得到的1-(2, 6-二氯苯基)-3-(甲基硫基)氧吲哚进行脱硫和水解。
