Reaction Steps

A mixture of methyl 3-bromobenzoate (1.0 g, 4.7 mmol), 2-(dicyclohexylphosphino)-2′-(N,N-dimethylamino)biphenyl (0.037 g, 0.093 mmol), tris(dibenzylidineacetone)dipalladium (0) (0.021 g, 0.023 mmol), anhydrous K3PO4 (1.4 g, 6.5 mmol) in 9.3 mL toluene under argon was added (S)—N,N-dimethylpyrrolidin-3-amine (0.71 mL, 5.6 mmol). The reaction was sealed and heated to 80 deg. C. for 3 days. The reaction was cooled to ambient temperature, was diluted with ethyl acetate, and filtered through celite. The filtrate was concentrated in vacuo to give a brown oil, which was further purified by silica gel chromatography, using 90/10/1 dichloromethane/methanol/sat'd ammonium hydroxide as eluent to give (S)-methyl 3-(3-(dimethylamino)pyrrolidin-1-yl)benzoate as a light brown oil.
