2‐Isonicotinoylacetophenone (1) reacts with aqueous ammonia in the presence of acid to produce the deep blue 3‐(4‐pyridyl)‐1‐[3‐(4‐pyridyl)‐1 H ‐1‐isoindolylidenemethyl]‐2 H ‐isoindole which changed to the deep bluish green adduct showing the wavelength maximum at 744 nm by treating with methyl iodide. From the reaction of 1 and glycine or its methyl ester the red 3,3′‐di‐(4‐pyridyl)‐1,1′‐vinylenebis(2 H ‐2‐isoindoleacetic acid) or its derivative were obtained respectively.
