Abstract
Oxone‐mediated oxidative 3‐arylthio substitution of indoles with benzenethiols in methanol has been succeeded, giving 3‐arylthioindoles. Indoles bearing a 2‐methyl group particularly exhibited higher activities toward 3‐arylthio substitutions. 3‐(2′‐Pyridylthio)indoles used as selective COX‐2 inhibitors were prepared in good to excellent yields.
