N-Alkylation of Aromatic Amines by Means of Alcohol. III. New Syntheses of N-Pyridylmethyleneaniline and Related Compounds

Abstract

A new synthesis of N-(2-pyridylmethylene) aniline (I) is described. The method consists of heating a mixture of 2-pyridinemethanol, aniline, and nitrobenzene in the presence of potassium hydroxide. Extension of the reaction to some related compounds was made. By-products accompanied with ortho-substituted derivatives of I were characterized as pyridylmethylene-bis-amines.
