Reaction Steps

A mixture of 4-amino-1-methylpiperidine (0.23 g), benzothiazol-2-yl(3-butoxyphenyl)methanol (0.63 g), sodium hydrogenocarbonate (2 mg) and dichloro(pentamethylcyclopentadienyl)iridium(III) dimer (8 mg) in toluene (3 mL) is heated in an autoclave at 110-120° C. for 66 hours. The mixture is purified by chromatography over silica gel (eluant dichloromethane/methanol: 98/2) to give the crude base, which is transformed to the oxalate in acetone to give [benzothiazol-2-yl(3-butoxyphenyl)methyl](1-methylpiperidin-4-yl)amine oxalate melting at 176° C.
