The possibility of non-catalytic -substitution of the halogen atom in the -position of the phenyl substituent in the C6 position of the 1,2,4-triazine ring by a cycloalkylamine group in the absence of a solvent was investigated. The possibility of transforming the obtained 1,2,4-triazines into the corresponding (bi)pyridines using the Bodger reaction with 2,5-norbornadiene under elevated pressure (using autoclave technology) was shown.
S.E. Vatolina (Wed,) studied this question.
