Procedure

4-Chloro-2-(3-formylphenoxy)benzonitrile (0.20 g, 0.78 mmol), n-propylamine (140 μL, 101 mg, 1.7 mmol) and sodium cyanoborohydride (60 mg, 0.96 mmol) were stirred at ambient temperature in a 1% acetic acid/methanol solution (20 mL) for 5 days. The solvent was removed in vacuo. The residue was treated with 10% sodium carbonate solution and extracted with ethyl acetate. The ethyl acetate layer was separated and fumaric acid (0.10 g, 0.86 mmol) was added. After the solvent was removed in vacuo, the residue was triturated with ethyl acetate overnight, collected by filtration, and dried to give 4-chloro-2-[3-(propylaminomethyl)phenoxy]benzonitrile fumarate (250 mg, 78%) as a white solid.
