New routes to the synthesis of pyridazinone, ethoxypyridine, pyrazole and pyrazolo[1,5-a]pyrimidine derivatives incorporating a benzotriazole moiety

摘要

A new approach to the synthesis of pyridazinone, ethoxypyridine, pyrazole and 7-aminopyrazolo-[1,5-a]pyrimidine derivatives. The structure of the newly synthesized compounds was elucidated by elemental analyses, ir, H-1 nmr spectra and in some cases by C-13 nmr investigations. [References: 13]
