A Mild and Efficient Synthesis of 3-Hetarylamino-s-Tetrazines

摘要

3,6-Bis(3,5-dimethylpyrazol-1-yl)-s-tetrazine reacts with weakly based hetarylamines such as aminofurazans, aminoimidazoles, aminotriazoles, aminotetrazoles, or aminotetrazines on heating in MeCN in the presence of M 2CO 3 (M = K, Cs) to afford 3-hetaryl- amino-s-tetrazines, the products of 3,5-dimethylpyrazolyl group displacement.
