Ethyl acetate (5 ml) and methanol (5 ml) were added to the reaction mixture, and the mixture was filtered through celite. The filtrate was concentrated under reduced pressure, and the resulting solid was collected by filtration, washed with tert-butyl methyl ether (5 ml) and dried under reduced pressure to give N-(4-{2-[4-(aminomethyl)-3-fluorophenyl]ethyl}-1,3-thiazol-2-yl)acetamide (119.3 mg, 0.407 mmol, yield 85.3%) as a white solid.
