Synthesis of some new pyrazolines from 4-amino-4-methoxybenzalace-tophenone as dyestuffs intermediates

New aminopyrazoline derivatives (II-V) has been obtained by the reaction of new benzalacetophenone derivatives (1a, 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 reactions and spectral data.
