Procedure

4-Chloro-2-(3-formyl-2-hydroxyphenoxy)-benzonitrile (0.30 g, 1.10 mmol), methylamine (2M in methanol, 2.5 mL, 5.0 mmol) and sodium cyanoborohydride (0.10 g, 1.6 mmol) were stirred at ambient temperature in a 1% acetic acid/methanol solution (35 mL) for 19 h. The solvent was removed in vacuo. The residue was treated with saturated sodium hydrogen carbonate solution and extracted with ethyl acetate. To the ethyl acetate layer was added fumaric acid (0.12 g, 1.03 mmol) and the solvent removed in vacuo. The residue was triturated with ethyl acetate overnight, collected by filtration, and dried to give 4-chloro-2-[2-hydroxy-3-(methylaminomethyl)phenoxy]-benzonitrile fumarate (256 mg, 58%) as a white solid.
