Versuchsvorschrift
A suspension of 1-(3-chloropropoxy)-4-iodobenzene obtained in Example 1-(1) (2.79 g), (R)-2-methylpyrrolidine (0.961 g), sodium iodide (0.282 g) and potassium carbonate (2.60 g) in acetonitrile (2.8 mL) was stirred in a sealed tube at 100° C. for 5 hours. The reaction mixture was cooled to room temperature, diluted with water and extracted with ethyl acetate. The organic layer was washed with water and brine, dried over sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluting solvent: n-hexane:ethyl acetate=10:1) to give the titled compound (3.27 g) as a yellow oil.
