Abstract
New series of benzotriazolo hydrazones(15-19) were synthesized from the reaction of hydrazide
of oxobenzotriazine (14) with some 4-aminobenzaldehydes (4-(pyrrolidin-1-yl)benzaldehyde (3), 4-(piperidin-1-yl)
benzaldehyde (4), 4-morpholinobenzaldehyde (5) and 4-(1H-pyrazol-1-yl)benzaldehyde (6). These aldehydes were
synthesized form the reaction of cyclic amines with 4-flourobenzaldehyde. The other type of aldehyde (7-methyl
2-oxo-1,2-dihydroquinoline-3-carbaldehyde) (10) was synthesized in three steps starting from m-toluidine which
was converted into amide (8), this amide was then transformed into (2-chloro-7-methylquinoline-3-carbaldehyde)
(9) via Vilsmeier reaction and finally into (7-methyl-2-oxo-1,2-dihydroquinoline-3-carbaldehyde) (10). The
synthesized compounds were studied using a combination of IR, NMR and Mass methods
