Versuchsvorschrift

A mixture of 6-hydroxy-2,4-bis(trichloromethyl)benzo[1,3]dioxin (1.0 g.) and acetic anhydride (10 ml.) was warmed on the steam bath for 15 minutes, and then cooled to ambient temperature. Water (40 ml.) was added, and the mixture stirred for 1 hour. The product was removed by filtration, washed with water, dried and crystallised from ethanol to give 6-acetoxy-2,4-bis(trichloromethyl)benzo[1,3]dioxin, m.p. 142°-144° C.
