Reaction Steps

4-(3,4-Dichlorophenoxy)-1-piperidinebutanoic acid hydrochloride (0.250 g) was dissolved in dichloromethane (10 mL) containing p-toluenesulfonamide (0.142 g), dimethylaminopyridine (92 mg) and EDCI (0.158 g) were added. The solution was stirred at room temperature for 4 days. The solvent was evaporated. The crude product was dried in vacuo and then purified by HPLC (at column dilution, gradient ammonium acetate/acetonitrile 75% to 5% ;Waters Xterra® column) and to give the title compound (42 mg).
