Reaction Conditions

Reaction Steps

A mixture of 2,4-bis(trichloromethyl)benzo[1,3]dioxin-6-diazonium chloride (5 g.) concentrated sulphuric acid (125 ml.) and water (125 ml.) was stirred and heated at 160° C. for 20 minutes. The reaction mixture was cooled to ambient temperature and the product was filtered off, washed with water, and crystallised from cyclohexane, to give 6-hydroxy-2,4-bis(trichloromethyl)benzo[1,3]dioxin, m.p. 167°-169° C.
