Procedure

To (2-chloro-benzyl)-(6-fluoro-pyridin-2-yl)-amine (16, 4.70 g, 19.8 mmol) in 100.0 mL of acetonitrile, N-bromosuccinimide (3.53 g, 19.8 mmol) in 20.0 mL of acetonitrile was added slowly at room temperature. The reaction was stirred at room temperature for 4 hours, then poured into aqueous potassium carbonate and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was washed with ethyl acetate in hexane to provide the desired compound (17, 5.0 g).
