Abstract :A novel series of Schiff base derivatives was synthesized starting from methylpiperazine through a multistep reaction sequence involving esterification, hydrazide formation, and condensation with various aromatic aldehydes. The resulting compounds (4a–g) were characterized by FT-IR, ¹H NMR, ¹³C NMR, and EI-MS spectroscopy, which confirmed the successful formation of the imine (C=N) linkage and the incorporation of functional groups such as methoxy, hydroxyl, halogen, and heteroaryl moieties. Spectral data revealed characteristic azomethine proton signals (7.19–8.93 ppm) and imine carbon stretches (1603–1623 cm⁻¹), consistent with Schiff base formation. Mass spectrometry further supported the molecular structures with well-defined molecular ion peaks and expected fragmentation patterns. The synthetic strategy afforded high product yields (81–93%) under mild conditions, demonstrating the efficiency of the condensation approach. The structural diversity and ease of modification suggest that these Schiff bases represent valuable scaffolds for further biological evaluation and materials research.
