Procedure

5-[4-(9H-9-Carbazolyl)-1-(3,4-dimethoxybenzoyl)-1,2,3,4-tetrahydro-2-quinolinyl]-1-pentanol (0.12 g, 0.22 mmol) prepared in Example 135 was mixed with 4-fluorophenol (50 mg, 0.44 mmol), tetrahydrofuran (4 ml), diethyl azodicarboxylate (69 μl, 0.44 mmol) and triphenylphosphine (0.11 g, 0.44 mmol), followed by stirring overnight at room temperature. After distilling off the solvent, the residue was partitioned between ethyl acetate and water, and the organic layer was washed with water, dried over anhydrous magnesium sulfate and then evaporated to remove the solvent. The residue was applied to silica gel column chromatography (developing solvent: ethyl acetate/hexane=1/10) to give the titled compound (0.13 g, yield: 93%) as a white crystal (cis:trans=4:1).
