Reaction Steps

To a suspension of (2R)-2-methylpyrrolidine (0.8 g) and cesium carbonate (1.7 g) in acetonitrile (5 mL), 1-(4-chlorobutoxy)-4-iodobenzene obtained in Example 61-(1) (1.4 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 (1.4 g, 89%) as a colorless oil.
