Substituted pyridines. preparation of substituted stilbazoles and their reactions

The condensation of 2,5-dimethyl-4-(β-phenylethyl)piperidine methiodide with aromatic aldehydes and also with phthalic anhydride has been performed. Geometrical isomers of 5-methyl-4-(β-phenyl-ethyl)-2-styrylpyridine have been isolated. The reactions of this substituted stilbazole at the styrene group have been studied. © 1970 The Faraday Press, Inc.
