実験手順

4-Chloro-2-(2-ethoxy-3-formylphenoxy)benzonitrile (0.55 g, 1.8 mmol), methylamine (2M in methanol, 3.0 mL, 6.0 mmol) and sodium cyanoborohydride (0.13 g, 2.1 mmol) were stirred at ambient temperature in a 1% acetic acid/methanol solution (55 mL) for 3 days. The solvent was removed in vacuo. The residue was treated with 10% sodium carbonate solution and extracted with ethyl acetate. Fumaric acid (0.21 g, 1.8 mmol) was added to the separated ethyl acetate layer and the solvent removed in vacuo. The residue was triturated overnight with ethyl acetate, collected by filtration, and dried to give 4-chloro-2-[2-ethoxy-3-(methylaminomethyl)phenoxy]benzonitrile fumarate (527 mg, 67%) as a white solid.
