Abstract

New aminopyrazo1ine derivatives (II-V) has been obtained by the reaction of new benzalacetophenone deriva- tives (Ia, b) with hydrazine hydrate and their derivatives. Further reactions were carried out on pyrazolines (VI-XI). The structural determination of the prepared compounds has been confirmed using elemental analysis, chemical reac- tions and spectral data.
