Versuchsvorschrift

Cool a solution of 4-aminobenzonitrile (0.48 g, 4.02 mmol) in pyridine (30 mL), to 0° C., and add 3-carboxymethoxy-benzoic acid methyl ester (0.79 g, 3.76 mmol) followed by phosphorous oxychloride (0.38 mL, 4.02 mmol). Stir the mixture at 0° C. for 2 h then dilute with water causing a solid to precipitate from solution. Collect the solid by filtration, wash with water, and dry on the filter pad to provide 1.01 g (81.0%) of 3-[(4-cyano-phenylcarbamoyl)-methoxy]-benzoic acid methyl ester.
