Reaction Steps

To a solution of 6-chloro-4-(2-chloro-benzyl)-2-trifluoromethanesulfonyloxy-quinoline-3-carboxylic acid ethyl ester (100 mg, 0.2 mmol) in THF (2 ml) was added potassium carbonate (109 mg, 0.79 mmol) and dimethylamine (2M solution in THF; 0.5 ml, 0.98 mmol) at 25° C. and the resulting reaction mixture was stirred at 70° C. for 3 h. The mixture was diluted with water (5 ml), and extracted with EtOAc (3×15 ml) and the organic phases were combined and washed with brine (15 ml), dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The crude residue was purified by column chromatography (3% EtOAc/hexane) to give 6-chloro-4-(2-chloro-benzyl)-2-dimethylamino-quinoline-3-carboxylic acid ethyl ester (55 mg, 69%) as pale yellow solid. LC-MS (ESI): 403 (M+H)+.
