To a suspension of (2R)-2-methylpyrrolidine (0.60 g) and cesium carbonate (1.2 g) in acetonitrile (3 mL), 1-(2-chloroethoxy)-4-iodobenzene obtained in Example 60-(1) (0.87 g) was added and the mixture was heated to 100° C., at which it was stirred for 9 hours. The reaction mixture was cooled to room temperature and filtered to remove insoluble materials, and the filtrate was concentrated under reduced pressure. The resulting residue was purified by NH-type silica gel column chromatography (eluting solvent: n-hexane:ethyl acetate=9:1 to 1:1) to give the titled compound (0.80 g, 78%) as a colorless oil.
