Abstract of the Disclosure This invention provides a novel process wherein 2,6-dimethoxyphenol reacts with a tertiary carbinol in the presence of an acid to provide exclusively a 1-hydroxy-2,6- dimethoxy-4-(quaternary alkyl)benzene, which when reacted with a halogenated disubstituted phosphite affords a novel 2,6-dimethoxy-4-(quaternary alkyl)phenyl disubstituted phosphate. Reduction of the phenyl phosphate derivative by reaction with an alkali metal affords a 1-(quaternary alkyl)- 3,5-dimethoxybenzene, which upon reaction with a demethylating agent provides a 5-(quaternary alkyl)resorcinol.
