FACILE PREPARATIONS OF 4-FLUORORESORCINOL

Two facile methods for preparing 4-fluororesorcinol have been developed.In the first method, the direct fluorination of 1,3-dimethoxybenzene with trifluoromethyl hypofluorite carried out in Freon 11 at -78 deg C afforded 2,4-dimethoxyfluorobenzene.Demethylation by heating under reflux in 48percent HBr in acetic acid gave 4-fluororesorcinol in an overall yield of 60percent.The second method involved the fluorination of 2,6-dimethoxycetophenone by trifluoromethyl hypofluorite in Freon 11 at -78 deg C, leading to 2,6-dimethoxy-3-fluorocetophenone.On heating under reflux in 48percent HBr in acetic acid, 4-fluororesorcinol was obtained in an overall yield of 74percent.The latter is the method of choice for preparing 4-fluororesorcinol.
