To a solution of bis(2-chloroethyl)-(3-phenylpropyl)ammonium chloride (0.593 g, 2 mmol) and 2-(2-fluorophenyl)ethanamine (0.278 g, 2 mmol) in dimethylformamide (6 mL) is added anhydrous potassium carbonate (0.829 g, 6 mmol) and sodium iodide (0.599 g, 4 mmol) successively. The reaction mixture is then stirred at 80° C. for 4.5 hours and then cooled to ambient temperature. Water and ethyl acetate are then added to the resultant reaction mixture. The organic layer is separated, washed 3 times with water and once with brine, dried over anhydrous magnesium sulfate, and concentrated. The residue is dissolved in ethanol. To this solution is added 6 N hydrochloric acid drop wise with cooling until pH 3. The resulting solution is maintained at 4° C. overnight. The resultant crystals are collected by filtration and washed with ethanol and ether to give 108 mg of the title compound (17%).
