A methodology for the syntheses of carboxanilides using solid support of 4-chloro-3-nitorbenzophenone oxime resin 5 was developed. Condensation of 4-chloro-3-nitorbenzophenone resin 6 with hydroxylamine hydrochloride salt gave oxime resin 5. The reaction of oxime resin 5 with dioxin and oxathiin derivatives 7a-d afforded the corresponding polymer-bound dioxin and oxathiin derivatives 9a-d. These polymer-bound resins 9a-d were treated respectively with aniline in the presence of acetic acid resulted in the corresponding dioxin carboxanilides 10a-d (yield, 5%-quantitative).
