Tetrazoles: XLVI. 3H-1,3,4-Benzo- and Pyrido[6,7-b][1,3,4]triazepines from 5-Aryltetrazoles. Synthesis and Chemical Properties
摘要:
2,5-Disubstituted 3H-1,3,4-benzotriazepines were synthesized by heating of N-imidoyltetrazoles in toluene at 110degreesC. Alkylation of these compounds, as well as of 3H-pyrido[6,7-b][1,3,4]triazepines with alkyl halides in THF in the presence of potassium tert-butoxide gave the corresponding 1-alkyl derivatives in good yield and with high regioselectivity.
