Reaction Steps

To a solution of 2,5-dibromo-3-phenylthiophene (2.54 g, 8.0 mmol) in dry THF (30 mL) at −65° C. was added LDA (8.8 mmol) dropwise. After stirring for 30 min at −65° C., oxirane (20.0 mmol) was added and the reaction was stirred for 2 h. The reaction mixture was then warmed to room temperature and water was added. The resulting mixture was extracted with EtOAc (3×100 mL), washed with brine, and dried over anhydrous Na2SO4. After filtration and concentration, the crude product was purified by column chromatography to give the title compound.
