Reaction Steps

To a solution of 4-chloro-2-(3-chloromethyl-2-ethyl-phenoxy)-benzonitrile (0.39 g, 1.3 mmol) in ethanol (20 mL) was added methylamine (33% in ethanol, 5.0 mL, 40 mmol), and the reaction mixture stirred for 24 h at ambient temperature. 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 a solution of fumaric acid (148 mg, 1.3 mmol) in methanol (5 mL) was added. After the solvent was removed in vacuo, the residue was triturated with diethyl ether overnight, collected by filtration, and dried to give 4-chloro-2-(2-ethyl-3-methylaminomethyl-phenoxy)-benzonitrile fumarate (455 mg, 86%) as a white solid.
