Procedure

4-Chloro-2-fluorobenzonitrile (0.567 g, 3.6 mmol), 3-dimethylaminomethyl-2-ethylsulfanyl-phenol hydrobromide (0.77 g, 2.6 mmol) and cesium carbonate (1.19 g, 3.6 mmol) were heated with stirring in dry DMF (4 mL) at 50° C. for 17 h. More cesium carbonate (1.19 g, 3.6 mmol) was added. After 1 h, the reaction was complete by LC/MS analysis. The reaction mixture was cooled, poured into water and extracted with ethyl acetate. The ethyl acetate layer was separated, washed with water (1×), 10% sodium carbonate solution (2×), water (2×), brine (1×), and dried over MgSO4. After filtration, the solvent was removed in vacuo to yield 4-chloro-2-(3-dimethylaminomethyl-2-ethylsulfanyl-phenoxy)-benzonitrile (662 mg, 52%) as a clear oil. Fumaric acid (30 mg, 0.26 mmol) in methanol (5 mL) was added to 4-chloro-2-(3-dimethylaminomethyl-2-ethylsulfanyl-phenoxy)-benzonitrile (91 mg, 0.26 mmol). The solvent was removed in vacuo and diethyl ether (20 mL) was added with stirring. After 17 h, 4-chloro-2-(3-dimethylaminomethyl-2-ethylsulfanyl-phenoxy)-benzonitrile fumarate (41.4 mg, 34%) was filtered off as a white solid.
