Reaction Steps
To a suspension of sodium hydride (60%; 32 mg, 0.8 mmol) in DMSO (3 ml) was added a solution of N-[4-chloro-2-(2-chloro-phenylethynyl)-phenyl]-malonamic acid ethyl ester (200 mg, 0.532 mmol) in DMSO (2 ml) under nitrogen at 25° C., and the reaction mixture was stirred for 2 h at 80° C. The reaction mixture was diluted with ethyl acetate (15 ml), and the organic layer was washed with brine (3×10 ml), dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to give a crude residue which was purified by flash column chromatography (20% EtOAc in hexane) to afford 6-chloro-4-(2-chloro-benzyl)-2-hydroxy-quinoline-3-carboxylic acid ethyl ester (63 mg, 32%) as an off white solid. LC-MS (ESI): 376 (M+H)+.
