実験手順

To a solution of 4-chloro-2-(2-chloro-phenylethynyl)-phenylamine (prepared as described in example 10 step A, 100 mg, 0.38 mmol) and 4-methyl-3-oxo-pentanoic acid ethyl ester (0.092 ml, 0.57 mmol) in anhydrous EtOH (10 ml), was added p-TsOH—H2O (72.56 mg, 0.38 mmol) and the mixture was refluxed for 72 h. After cooling, the reaction mixture was diluted with ethyl acetate and the organic layer was washed with saturated sodium bicarbonate solution and brine, dried over sodium sulfate, concentrated in vacuo. The crude residue was purified by flash column chromatography (elution with 3% EtOAc in hexane) to give 6-chloro-4-(2-chloro-benzyl)-2-isopropyl-quinoline-3-carboxylic acid ethyl ester (35 mg, 23% yield) as a yellow sticky solid. LC-MS: 402 (M+H)+.
