Abstract

PURPOSE: To prepare the titled compound useful as an intermediate of dyes, pharmaceuticals, pesticides, etc., in a short time, by the reductive alkylation of an aromatic amino compound in the presence of a noble metal catalyst and hydrogen in an organic solvent under the controlled rate of feeding of an aldehyde compound.
CONSTITUTION: An aromatic amino compound (e.g. o-toluidine, 2-aminophenol, etc.) is alkylated with an aldehyde compound (e.g. formaldehyde, benzaldehyde, etc.) as the alkylating agent, in an organic solvent, in the presence of a noble metal catalyst (e.g. palladium-activated charcoal, platinum-activated charcoal, etc.) and hydrogen. The aldehyde compound is supplied to the reaction system corresponding to the consumption of hydrogen excepting the induction period. The reaction is carried out at normal temp. W150°C, pref. 50W100°C under atmospheric pressure or positive pressure (usually ≤10atm.) controlled with hydrogen.
