Methylamine → HCID 21930354, compound

Participants

Reaction Steps

To a solution of 4-chloro-2-(3-chloromethyl-4-fluorophenoxy)-benzonitrile (0.14 g, 0.47 mmol) in ethanol (15 mL) was added methylamine (33% in ethanol, 4.0 mL, 32 mmol), and the reaction mixture stirred for 10 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 (50 mg, 0.43 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 4-chloro-2-(4-fluoro-3-methylaminomethyl-phenoxy)-benzonitrile fumarate (183 mg, 95%) as a white solid.
