Reaction Steps

A solution of diethyl(3-bromophenyl)fluoromethylphosphonate (2.1 g, 6.5 mmol) in 50 mL of THF was added dropwise via syringe to a solution of LDA (5 mL, 10 mmol) in THF at −78° C. under N2 atmosphere. After 30 min at this temperature methyl 4-formylbenzoate (1.1 g, 6.5 mmol) in 50 mL of THF was added dropwise via syringe and then stirred at this temperature for 30 min and then allow warm to room temperature over 4 hours, and stirred overnight. The mixture was poured into H2O (300 mL) and then extracted with ethyl acetate (3×100 mL). The combined organic layer was concentrated and purified by silica gel chromatography (eluting with a mixture of petroleum ether and ethyl acetate=50:1) to give (Z)-methyl 4-(2-(3-bromophenyl)-2-fluorovinyl)benzoate (0.73 g, 33.6%) as a yellow oil.
