METHOD FOR MAKING AMINOPHENOLS AND THEIR AMIDE DERIVATIVES ABSTRACT N-acylated dialkylaminophenols are produced at greater yields under mild reaction conditions by a novel process which begins with catalytic hydrogenation of dialkylnitrosophenols in an aprotic organic reaction medium. Acylation can subsequently be carried out without isolation of the aminophenol from the reaction medium.
