Procedure: 3-(3,5-dichlorophenyl)-3-(trifluoromethyl)pyrrolidine (0.6 g) and 2-fluoro-5-iodobenzonitrile (0.57 g) was dissolved in toluene, which was then degassed 3 times. To the solution in toluene was added sodium tert-butoxide (0.20 g), Tris(dibenzylidene acetone)dipalladium chloroform complex (0.04 g) and Xantphos (0.07 g) under argon atmosphere, and the mixture was stirred at 80° C. for two hours. The mixture was cooled to room temperature and then diluted with ethyl acetate, which was then washed with water and dried over anhydrous magnesium sulfate. After the drying agent was filtered off, the solvent was distilled away under the reduced pressure, and the residue was then purified by silica gel chromatography to yield 5-[3-(3,5-dichlorophenyl)-3-(trifluoromethyl)pyrrolidin-1-yl]-2-fluorobenzonitrile (0.54 g). m.p. 184-186° C. which was then degassed 3 times To the solution in toluene was added sodium tert-butoxide (0.20 g), Tris(dibenzylidene acetone)dipalladium chloroform complex (0.04 g) and Xantphos (0.07 g) under argon atmosphere The mixture was cooled to room temperature diluted with ethyl acetate, which was then washed with water dried over anhydrous magnesium sulfate After the drying agent was filtered off the solvent was distilled away under the reduced pressure the residue was then purified by silica gel chromatography

Procedure: Add bis(triphenylphosphine)palladium (II) dichloride (77 mg, 0.11 mmol), copper (I) iodide (42 mg, 0.22 mmol), and 3-chloro-5-ethynylpyridine, (prepared as described in PREPARATION 27), (300 mg, 2.2 mmol) to a solution of 2-fluoro-5-iodobenzonitrile (650 mg, 2.6 mmol) in triethylamine (4.6 mL, 33 mmol) and heat at 60° C. for 6 h. Cool to room temperature and concentrate. Purify by silica gel chromatography, eluting with 50:50 dichloromethane:hexanes to 90:10 dichloromethane:ethyl acetate, followed by a second silica gel chromatography eluting with 95:5 to 75:25 hexanes:ethyl acetate, to give the title compound as an off-white solid (510 mg, 91%). Cool to room temperature concentrate Purify by silica gel chromatography eluting with 50:50 dichloromethane eluting with 95:5 to 75:25 hexanes

Procedure: Sodium thiomethoxide (0.142 g) was added to a solution of 2-fluoro-5-iodobenzonitrile (0.5 g) in DMSO (1 mL) and the mixture stirred. An exotherm was noted. After stirring for 90 min, water was added and the solid that precipitated was collected, washed with water and dried at 50° C. under vacuum to leave the subtitle compound as an off-white solid (0.52 g). After stirring for 90 min the solid that precipitated was collected washed with water dried at 50° C. under vacuum
