Reaction Steps
A mixture of sodium hydride (0.20 g) and n-butanol (10 mL) was treated with 4-fluorothiophenol (0.64 g), and the resulting mixture was added to a mixture of 3-bromothiophene-2-carbaldehyde (0.96 g), tetrakis(triphenylphosphine)palladium (0) (0.12 g) and n-butanol (5.0 mL). The resulting mixture was stirred at 100° C. for 2 hours and then at 120° C. for 4 hours. The mixture was cooled to room temperature, concentrated under reduced pressure and the residue partitioned between water and ethyl acetate. The aqueous phase was extracted with ethyl acetate, and the combined organic solution was dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with a mixture of cyclohexane and dichloromethane (2:1 to 0:1 by volume) to afford the title compound as a yellow solid (0.78 g).
