実験手順

To a stirred solution of 3-{2-[4-(2-methyl-5-quinolinyl)-1-piperazinyl]ethyl}aniline (D6, 30 mg) in pyridine (0.5 mL) was added 2-chloroethylsulfonyl chloride (13 μL). The mixture was stirred 1 h then concentrated in vacuo and partitioned between saturated aqueous sodium hydrogencarbonate solution and DCM. The organic layer was washed (water), dried (sodium sulfate) and concentrated in vacuo. The residue was dissolved in THF (1 mL) and cooled to 0° C. with stirring. To the stirred solution was added sodium hydride (60%, 20 mg). The mixture was warmed to room temperature and left to stand for 4 days. The reaction was diluted with water and concentrated in vacuo. The residue was partitioned between DCM and water. The organic layer was washed (water), dried (sodium sulfate) and concentrated in vacuo. The residue was purified by column chromatography (SiO2; EtOAc) to give the title compound (4.4 mg).
