Reaction Steps

To a solution (25 mL) of 2-chloro-4-fluoro-5-methylbenzonitrile (848 mg) in dimethyl sulfoxide were added 0.9M-dimethyl sulfoxide solution (5.56 mL) of (2S,3S)-3-hydroxy-2-methylpyrrolidine and lithium carbonate (370 mg), and the mixture was stirred at 100° C. for 1 hr. Water was added and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (developing solvent: hexane-ethyl acetate) and crystallized from ethyl acetate-hexane to give the title compound as a colorless solid (yield: 374 mg).
