Procedure

0.49 ml of 3-chloropropanesulfonyl chloride was dropwise added, at 0° C., to a solution of 1.19 g of 1-(2-cyclooctylaminoethyl)-4-methoxymethoxypiperidine and 0.67 ml of triethylamine in 10 ml of dichloromethane. The mixture was stirred at room temperature for 1 day. The reaction mixture was washed with water and dried with magnesium sulfate. The solvent was removed by distillation. The resulting residue was purified by silica gel column chromatography (eluant: 2% methanol/dichloromethane) to obtain 1.2 g of 1-{2-[N-(3-chloropropylsulfonyl)-N-cyclooctylamino]-ethyl}-4-methoxymethoxypiperidine.
