Reaction Steps

To a solution of (4S,5S)-1-(3-chloro-4-iodophenyl)-3,3-difluoro-4-hydroxy-5-methylpyrrolidin-2-one (113 mg) in DMF (3.5 mL) were added zinc cyanide (12 mg) and tetrakis(triphenylphosphine)palladium(0) (34 mg), and the mixture was stirred at 100° C. for 4 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:hexane/ethyl acetate=30/1→1/2) to give the title compound as a colorless solid (yield: 75 mg, 90%).
