Procedure
A solution of sodium ethoxide (21% by weight in EtOH, 0.68 gm, 10 mmol) was added to a solution of 2-acetylthiophene (12.60 gm, 100 mmol, from Aldrich) and 4-fluorobenzaldehyde (12.41 gm, 100 mmol, from Aldrich) in EtOH (50 ml) and the mixture stirred under argon for 15 minutes. More EtOH (25 ml) was then added to make a slurry of the reaction mixture, which had partially solidified. Acetic acid (0.60 gm, 11 mmol) was added and a yellow solid filtered out of solution. The solid was recrystallized from EtOAc and hexane to afford the title compound as long, pale yellow needles (17.679 gm, 71%).
