| Abstract | ||
| In this study some new derivatives of thiazole compounds were successfully prepared in two steps with high yields. The first step included a synthesis of a new series of pyrazoline (1a-1i) using a one-pot three components reaction. The reaction between (acetophenone4-nitroacetophenone), different substituted benzaldehyde compounds and thiosemicarbazide in absolute ethanol as a solvent with heating at reflux provided the new series of pyrazoline derivatives in a short reaction times. In the second step, the pyrazoline compounds (1a-1i) refluxed with 4-bromophenacyl bromide in absolute ethanol to produce thiazole compounds (2a-2i) in high yields. The Infra-red technique (FT-IR) was used to identify the synthesised compounds and the proton Nuclear Magnetic Resonance technique (1H-NMR) was used to identify som of them. . | ||
