2-(1-Bromovinyl)pyridine, 2-ethynylpyridine, 2-(1-alkoxyvinyl)pyridines, and 2-(2-alkoxyvinyl)pyridines (the cis and trans isomers) were detected in the reaction mixture by mass spectrometry in the reaction of 2-vinylpyridine with bromine with subsequent dehydrobromination of the addition product with an alcohol solution of alkali. The conditions for the preparation of chromatographically pure compounds were found.
