Abstract
A method for the introduction of the N , N -dimethylformamidine protective group in a series of six-membered 2-aminohetarene N -oxides was developed. It was shown that 2-amino derivatives of N -oxides of various six-membered heterocycles (pyridines, pyrimidines, pyrazines, tetrazines) successfully enter the reaction. The stability of the N , N -dimethylformamidine protecting group in 2-aminohetarene N -oxides was found to depend on the type of reaction medium.
