Reaction Steps

To a 150 mL pressure vessel was added ethyl 2-chloronicotinate (3.1 g, 17 mmol), 4-(pyridin-2-ylamino)phenol (3.14 g, 17 mmol), and cesium carbonate (5.8 g, 18 mmol) followed by DMSO. The solution was sealed and heated to 100° C. for 20 h. It was cooled and diluted with water and extracted five times with ethyl acetate. The combined organic were washed with brine, dried over sodium sulfate, filtered, and concentrated to a dark brown residue. The residue was taken up in dichlormethane and adsorbed onto silica gel before being purified with flash chromatography (0 to 50% ethyl acetate:hexanes), affording the product as a pale orange solid. MS (ESI, pos. ion) m/z: 336.0 (M+1).
