Studies with 1-functionally substituted alkylbenzotriazoles: An efficient route for the synthesis of 1-azolylbenzotriazoles, benzotriazolylazines and benzotriazolylazoloazines

A new approach to the synthesis of pyrazole, isoxazole, pyridine and pyrazolo[1,5-a]pyrimidine derivatives is reported. The structure of the newly synthesized compounds was elucidated by elemental analyses, ir and H-1 nmr spectra, and in some cases by C-13 nmr investigation.
