A mixture of 1-(6-chlorobenzothiazole-2-yl)pyrrolidine-3-ylamine (2.49 g), 2-nitrobenzenesulphonyl chloride (2.40 g), triethylamine (3.02 mL) and dimethylformamide (15 mL) was stirred at 60° C. for 3 hours. To the reaction solution was added water and extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over sodium sulphate. The solvent was evaporated under reduced pressure and the residue was purified by column chromatograph on silica gel to give the title compound (2.01 g). Yield: 47
