Procedure

To a solution of 1,2,3-triazole (36.5 mg) in N,N-dimethylformamide (1 mL) is added a dispersion of sodium hydride 60% in mineral oil (1 molar equivalent). The reaction mixture is stirred at room temperature for 15 minutes, then a solution of methanesulfonic acid 2-{3-[benzothiazol-2-yl(1-methylpiperidin-4-yloxy)methyl]phenylsulfanyl}ethyl ester (85 mg) in N,N-dimethylformamide (1 mL) is added. The reaction mixture is stirred at 60° C. overnight. Water is added and the aqueous phase is extracted by ethyl acetate. The organic phase is dried over magnesium sulfate and concentrated under reduced pressure. The residue is purified by column chromatography (gradient dichloromethane/methanol/ammonia 100/0/0 to 90/10/1) to afford 2-{(1-methylpiperidin-4-yloxy)[3-(2-[1,2,3]triazol-2-yl-ethylsulfanyl)phenyl]methyl}benzothiazole.
