1) Nitration and bromination of β-resorcylic acid and its 4-methyl ether revealed that the nitro or bromine group is introduced into the 5-position.
2) Methylation of 5-bromo- and 5-nitro-β-resorcylic acid with dimethyl sulfate showed that the hydroxyl in the ortho-position of bromine or nitro group is more easily methylated than that ortho to the carboxyl group, apart from the behavior of the carboxyl.
3) Orientation of the β-substituted compound of resorcinol was discussed, with emphasis on the aromaticity of resorcinol in the case of free hydroxyl, monoether, and diether.
