Synthesis and characterization of some new hydrazides and their derivatives

الملخص EN

New hydrazide compounds (A2) and (A9) were prepared from their corresponding esters (A1, A8) .These esters were also prepared from their precursors 5-ethoxy carbonyl-(4- methoxyphenyl)-6-methyl-1,2,3,4-tetrahydropyrimidine-2-thione (A1) via multicomponent reaction type and from hippuric acid respectively.

The hydrazide compounds were then allowed to react with some aldehydes forming the corresponding hydrazones (A3-7) and (A10- 14).

The synthesized compounds were characterized by IR, 1H-NMR, 13C-NMR, and Mass spectroscopies and well discussed.
