Abstract

In this paper , a number of heterocyclic compounds with five-memberd pyrazolines were
prepared , the ester compound (1) was synthesized from the reaction of benzotriazole with
ethyl chloroacetate , the hydrazide (2) was prepared from the reaction of ester (1) with
hydrazine hydrate , benzelidene acetone (9-3) was prepared from the reaction of
condensation aldol , from the reaction one mole from acetone with tow mole from different
benzaldehyde in sodium hydroxide as alkalinity , after that pyrazolines ring was prepared
from reaction with Di benzelidene acetone from benzotriazole hydrazine acetate in sodium
hydroxide (16-10) , these compound were studied and identified by physical and spectral
methods .
