Reaction Steps

The 4-tosyloxyethyl-N-(4-nitrophenyl)piperidine (2.02 g, 5.0 mmol) obtained in Example 6(2) was dissolved in acetonitrile (20 ml), and potassium carbonate (1.38 g, 10 mmol) and morpholine (0.65 ml, 7.5 mmol) were added thereto, followed by stirring at 80° C. for 15 hours. After the reaction mixture was allowed to cool to room temperature, ethyl acetate was added to the reaction mixture, and the organic layer was washed with water and saturated sodium chloride, and dried over anhydrous sodium sulfate. After the desiccant was filtered off, the residue obtained by evaporation under reduced pressure was purified using medium pressure silica gel flash column chromatography (methanol:chloroform=1:50 to 1:20), thereby obtaining 4-morpholinoethyl-N-(4-nitrophenyl)piperidine (1.23 g, 77%) as a yellow solid.
