| Abstract | ||
| In this work ester compound [H2] has been prepared by reaction 1-Nitroso-2-Naphthol with ethyl α-bromo acetate , Then ester compound [H2] reacted with hydrazine hydrate(98%) to gavehydrazide compound [H3] .The treatment of hydrazide [H3] with some aldehydes or ketones gave corresponding azomethen compound [H4-H7] which converted to compounds [H8-H9] or to [H10-H11] when reacted with acetyl chloride or with 2,4-dinitrobenzoyl chloride respectively . on other side , the treatment of hydrazide [H3] with phenyl isothiocynate gave thiosemicarbazide derivative [H12] which on dissolve in solution of sodium hydroxide(2N) then neutralized with HCl gave traizole compound [H13] . The reaction of triazole [H13] with suitable secondary amines gave compounds [H14-H16] . As well as , the treatment of thiosemicarbazide [H12] with anhydrous ortho phosphoric acid gave compound [H17] .In addition the reaction of thiosemicarbazide [H12] with phynacyl bromide gave compound [H18]. | ||
