A mixture of 6-hydroxy-2,4-bis(trichloromethyl)benzo[1,3]dioxin (1.0 g.), benzoyl chloride (0.35 ml.) and toluene (20 ml.) was warmed on the steam bath for 1 hour. The resulting solution was cooled to ambient temperature and evaporated to dryness under reduced pressure to give an oily residue. The residue was triturated with ethanol (5 ml.) to give a white solid, which was crystallised from ethanol to give 6-benzoyloxy-2,4-bis(trichloromethylbenzo[1,3]dioxin, m.p. 167°-169° C.
