Versuchsvorschrift

3-[(3-chloro-4-fluoro-benzimidoyl)-amino]-4-methoxy-benzoic acid methyl ester (3.24 g, 9.62 mmol) was dissolved in 50% methanol and 5% NaOCl (18 ml, 11.90 mmol) was added dropwise thereto at room temperature. After 5 min, Na2CO3 (2.04 g, 19.25 mmol) was added dropwise thereto and refluxed for 5 min. The resulting solution was cooled to room temperature, extracted with ethyl acetate, and the extract was concentrated under a reduced pressure. The resulting residue was purified by silica gel column chromatography to obtain the title compound (0.95 g, 2.83 mmol) in a yield of 30%.
