1-(2,5-Dimethyl-3-thienyl)-3-(2,4,5-trimethoxyphenyl)prop-2-en-1-one

The title compound, 1-(2,5-dimethyl-3-thienyl)-3-(2,4,5-trimethoxy­phenyl)prop-2-en-1-one (3) was synthesized in high yield by an aldol condensation reaction of 3-acetyl-2,5-dimethythiophene and 2,4,5-trimethoxybenzaldehyde in methanolic NaOH at room temperature. Its structure was fully characterized by elemental analysis, IR, 1H NMR, 13C NMR and EI-MS spectral data.
