Abstract
PURPOSE: To prepare a stabilized title compound useful as an intermediate of pharmaceuticals and pesticides, easily, in high yield, by reacting p-nitrotoluene with sodium polysulfide, and extracting the title compound with a halogenated benzene.
CONSTITUTION: p-Nitrotoluene is made to react with sodium polysulfide in a mixed solvent of alcohol and an aqueous solution of alkali, in the presence of an aportic polar compound. Stable-p-aminobenzaldehyde can be propared by extracting the reaction mixture containing the aldehyde with a halogenated benzene (e.g. monochlorobenzene, etc.).
EFFECT: Undesirable condensation of the objective compound can be prevented.
