Abstract

m-Hydroxydiphenylamine derivatives are obtained by condensing 1-methyl-2-amino-4-hydroxybenzene with aromatic amines not containing nitro, sulphonic, or carboxylic groups, in the presence of hydrochloric acid or an agent yielding it. According to examples, 1-methyl-2-amino-4-hydroxybenzene is condensed with aniline, p-toluidine, and p-chloraniline to give the corresponding m-hydroxydiphenylamine derivatives.
