(E)-3-Methyl-6-(3-oxo-3-(thiophen-2-yl)-1-propenyl)-2(3H)-benzothiazolone

The title compound, (E)-3-methyl-6-(3-oxo-3-(thiophen-2-yl)-1-propenyl)-2(3H)-benzothiazolone, was synthesized by Claisen-Schmidt condensation of 3-methyl-2(3H)-benzothiazolone-6-carbaldehyde with 2-acetylthiophene in 94% yield. The structure of the target compound was confirmed using H-1-NMR, C-13-NMR, IR, MS, and elemental analysis.
