对二甲氨基苯甲酰肼 | 4-(dimethylamino)benzohydrazide | 19353-92-5 | C9H13N3O | 179.222 |
Reaction of 4-pyridinecarboxaldehyde with 3-hydroxy-4-methoxybenzohydrazide, 4-bromobenzohydrazide and 4-dimethylaminobenzohydrazide, respectively in methanol afforded three new benzohydrazones. They are 3-hydroxy-4-methoxy-N’-(pyridin-4-ylmethylene)benzohydrazide (1), 4-bromo-N’-(pyridin-4-ylmethylene)benzohydrazide (2), and 4-(dimethylamino)-N’-(pyridin-4-ylmethylene)benzohydrazide (3). The compounds have been characterized by elemental analysis, 1H and 13C NMR and IR spectroscopy, as well as single crystal X-ray diffraction. The antibacterial activities of the compounds against E. coli, P. aeruginosa, B. subtilis, and S. aureus were investigated and gave interesting results.
