| titleOfInvention | PROCESS FOR PREPARING PYRAZOLYL SUBSITUTED TETRAZONE DERIVATIVES |
| abstract | The invention describes a process for the preparation of pyrazolyl-substituted tetrazole derivatives. Heterocycles of this type are of interest as intermediates for the synthesis of biologically active compounds. The title compounds are prepared according to the invention by reacting * (formula I) in solvents such as acetonitrile or benzene with carbonyl halides (formula II) in the presence of equimolar amounts of an auxiliary base such as pyridine or triethylamine at temperatures up to the boiling point of the reaction mixture and the * (formula III) with hydrazine or arylhydrazines (formula IV) in boiling alcoholic solution in the presence of an acid, for. As acetic acid, brings to the reaction. {* Intermediates; * Carboxylic acid halides; pyridine; triethylamine; * Hydrazine; arylhydrazines; Acetic acid} |
