実験手順

7N Ammonia in methanol (30 mL, 210 mmol) was added to 4-chloro-2-(3-chloromethyl-2-methysulfanyl-phenoxy)-benzonitrile (240 mg, 0.8 mmol). After stirring for 17 h, TLC still showed some 4-chloro-2-(3-chloromethyl-2-methysulfanyl-phenoxy)-benzonitrile. The reaction mixture was concentrated to about 10 mL by evaporation in vacuo, concentrated ammonia (7 mL) was added and the mixture was heated with stirring at 60° C. for 17 h. Sodium carbonate solution (4 mL) and ethyl acetate (6 mL) were added and the organic layer was separated and dried with MgSO4. To this, was added fumaric acid (84 mg, 0.64 mmol) in methanol (3 mL). Immediately, the solvent was removed in vacuo and diethyl ether (40 mL) was added to the residue. After stirring for 17 h, 4-chloro-2-(3-aminomethyl-2-methysulfanyl-phenoxy)-benzonitrile fumarate (134.7 mg, 53%) was filtered off as a white solid.
