The Synthesis of Benzo(d)pyrido(a)-benzimidazole-5,12-quinone
The present investigation yielded an orange product upon refluxing 2-butyramido-3-chloro-1,4-naphthoquinone and 2-aminopyridine in ethanol. When this material was purified, by recrystallization from glacial acetic acid, the melting point was 306 [degrees]. This compound has been shown to be benzo(d)pyrido(a)-benzimidazole-5,12-quinone by the present investigation.

The Preparation of Pyridinium Derivatives by the Knoevenagel Condensation
An attempt is made in the work described in this paper to extend the series started by Hall and Platas by means of a Knoevenagel condensation between 3-hydroxy-1,4-naphtho-quinone-2-(4-methylpyridinium) anhydride and various aromatic aldehydes giving rise to a series of unsaturated substituents on the four position of the pyridine ring.
