Abstract
PURPOSE: To prepare the title compound useful as a photo-developing agent, antioxidant, etc., economically, without side reactions, by reducing o- or p-quinonemonoimine with an N,N-di-substituted hydroxylamine.
CONSTITUTION: An o- or p-quinonemonoimine derivative of formula I (X is H, substituted or unsubstituted alkyl, alkoxy, N-alkylcarbamoyl, acyl, etc.; Y is the same definition as X, or condensed ring) or formula II (R is substituted or unsubstituted alkylsulfonyl, arylsulfonyl, acyl, etc.), is reduced with an N,N-di-substituted hydroxylamine of formula III (R1,2 are substituted or unsubstituted alkyl or cycloalkyl), e.g. N,N-diethylhydroxylamine, to afford the objective compound of formula IV or V.
