Procedure
A mixture of 2-bromo-4-chlorobenzonitrile (500 mg, 2.31 mmol), (S)-N,N-dimethylpyrrolidin-3-amine (317 mg, 2.77 mmol), cesium carbonate (1505 mg, 4.62 mmol), tris(dibenzylideneacetone)dipalladium(0) (212 mg, 0.23 mmol) and BINAP (288 mg, 0.46 mmol) in toluene (15 mL) was stirred at 100 °C for overnight. Conc. in vacuo, the residue was purified with ISCO (100% ethyl acetate to 30% methanol in ethyl acetate) to yield a light yellow solid as (S)-4-chloro-2-(3-(dimethylamino)pyrrolidin-1-yl)benzonitrile (400 mg, 69.3 %).
