Shidlovskii, A. Sizov, L. Kuleshova, V. Nesterov, M. Antipin, A. Peregudov, N. Chkanikov] Reactions of 2-chloro-1-cyano-2-trifluoromethylethylenes with 2-aminopyridines were studied. According to the data of NMR spectroscopy and X-ray diffraction analysis, the first stage of the reaction involves alkenylation of the exocyclic nitrogen atom of 2-aminopyridines followed by formation of pyrido[1,2-a]pyrimidines.
