Conditions

Temperature: 80 °C

Procedure

A mixture of [3-[[1-(6-chlorobenzothiazole-2-yl)pyrrolidine-3-ylamino]methyl]phenyl]acetic acid methyl ester (68 mg), 1-iodobutane (37 μL), potassium carbonate (45 mg) and dimethylformamide (1 mL) was stirred at 80° C. for 3.5 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 residue was purified by column chromatograph on silica gel to give the title compound (28 mg). Yield: 36%.
