Reaction Steps

A 50 mL round bottom flask was charged with a magnetic stir bar, 3-bromo-2-fluorobenzaldehyde (0.555 g, 2.73 mmol), (S)-N,N-dimethylpyrrolidin-3-amine (0.312 g, 2.73 mmol), DMSO (5.47 ml), and potassium carbonate (0.378 g, 2.73 mmol). The mixture was heated to 85° C. overnight with stirring. The reaction was allowed to cool to ambient temperature, was diluted with water, and extracted into methylene chloride. The combined organic extract was dried with MgSO4, filtered, and conc. in vacuo to provide the product which was purified via silica gel chromatography (40 g) using ethyl acetate/MeOH (10:1) as eluent to afford (S)-3-bromo-2-(3-(dimethylamino)pyrrolidin-1-yl)benzaldehyde (0.369 g, 45.4%).
