実験手順

A mixture of 1-(4-chloro-2-phenylaminophenyl)-ethanone (1.7 g, 6.9 mmol), 4-formyl-benzoic acid methyl ester (1.14 g, 6.9 mmol) and NaOH (2 M aq, 2 mL) in MeOH (30 mL) was stirred at RT overnight. The precipitate formed was collected by filtration and dried in a vacuum oven to afford 0.7 g of 4-[(E)-3-(4-chloro-2-phenylamino-phenyl)-3-oxo-propenyl]-benzoic acid methyl ester as an orange solid. The mother liquors were acidified by adding glacial HOAc (99%) to pH 5, and the resulting mixture extracted with EtOAc. The combined organic extracts were dried over Na2SO4, filtered and evaporated under reduced pressure to yield 4-[(E)-3-(4-chloro-2-phenylamino-phenyl)-3-oxo-propenyl]-benzoic acid (350 mg).
