Abstract
A process for producing a p-hydroxyneophyl m-phenoxybenzyl ether represented by the general formula (II) ##STR1## (X.sub.1 and X.sub.2 are independently a hydrogen atom or a halogen atom) by subjecting a corresponding p-alkoxyneophyl m-phenoxybenzyl ether represented by the general formula (I) ##STR2## (R represents a lower alkyl group, and X.sub.1 and X.sub.2 have the same definitions as above) to ether cleavage, in which process the ether cleavage reaction is effected in an aprotic polar solvent, using a lower alkoxide of an alkali metal or an alkaline earth metal or using a metal hydroxide in the presence of a lower alcohol.
