Reaction Steps

To a solution of 4-chloro-2-(3-chloromethyl-2-ethyl-phenoxy)-benzonitrile (0.16 g, 0.53 mmol) in methanol (10 mL) was added ammonia (7N in methanol, 15 mL, 105 mmol), and the reaction mixture stirred for 4 days 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 (60 mg, 0.52 mmol) in methanol (3 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 2-(3-aminomethyl-2-ethyl-phenoxy)-4-chloro-benzonitrile hemifumarate (174 mg, 83%) as a white solid.
