HCID 5964663-Dimethylamino-1-thien-3-ylpropen-1-oneAusbeute 87 %

Versuchsvorschrift

A mixture of 48.4 g of 3-acetylthiophene and 75 ml of dimethylformamide dimethyl acetal, under nitrogen, is heated for 15 hours on a steam bath. The reaction is concentrated in vacuo and the residue crystallized from methylene chloride/hexane to give 60.55 g (87%) of the desired product, mp 89°-90° C.
