実験手順

To a mixture of 3-iodopyridine (1.12 g, 5.46 mmol) and 3,3-diphenylpropan-1-amine (1.72 g, 8.14 mmol) was added potassium carbonate (1.49 g, 10.8 mmol), copper(I) iodide (0.126 g, 0.662 mmol), (S)-pyrrolidine-2-carboxylic acid (0.154 g, 1.34 mmol), and DMSO (3.5 mL). The reaction mixture was heated to 75° C. for 18 h and diluted with EtOAc. The organic phase was washed with water (1×), brine (1×), dried over MgSO4, filtered, and concentrated. Purification by flash column chromatography on silica gel (eluted with 30% to 80% EtOAc in hexanes) gave N-(3,3-diphenylpropyl)pyridin-3-amine.
