Reaktionsschritte

To a solution of 2-chloro-3-fluoropyridin-4-ylamine (1.05 g, 7.1 mmol) in DMF (25 mL) at 0° C. was added sodium hydride (0.343 g, 14.3 mmol). The resulting violet mixture stirred for 20 minutes before a solution of 2-chloro-4-cyano-6-fluoro-benzoyl chloride (1.87 g, 8.6 mmol) in DMF (10 mL) was added. The mixture was warmed to room temperature stirred for 16 hours, then quenched with water and 1M HCl. The mixture was filtered through Celite®, washing with EtOAc. The organic filtrate was dried over Na2SO4 and concentrated under reduced pressure. The resultant residue was purified by silica gel flash chromatography eluting with DCM to give the desired compound as an off-white foam (0.869 g, 25% yield). 1H NMR (300 MHz, CDCl3): δ 8.24 (d, J=5.1 Hz, 1H), 7.55 (s, 2H), 7.36 (d, J=8.0 Hz, 2H), 7.32-7.23 (m, 1H).
