100 °C

A mixture of 1-(4-fluorophenyl)-2-(pyridin-4-yl)-ethan-1-one (5.12 g) and N,N-dimethylformamide dimethyl acetal (16 ml) was stirred at 100° C. for 3 hours under nitrogen. The cooled mixture was concentrated in vacuo. The residue was crystallized from isopropyl ether to yield 3-dimethylamino-1-(4-fluorophenyl)-2-(pyridin-4-yl)-2-propen-1-one (6.15 g).
