Procedure
To a stirred solution of 4-[5-nitro-1H-indol-3-ylmethyl]-3-methoxy-benzoic acid methylester (1.30 grams, 3.82 mmol) and 4-dimethylaminopyridine (0.58 mL, 4.77 mmol) in methylene chloride (60 mL) was added 4-fluorophenylisocyanate (0.70 mL, 5.73 mmol). The resulting solution was stirred for 18 hours, at room temperature, and then diluted with methylene chloride. The solution was washed with 1 M hydrochloric acid, water and brine, then dried over magnesium sulfate. Concentration in vacuo followed by trituration in diethylether gave 4-[1-(4-fluoro-phenylcarbamoyl)-5-nitro-1H-indol-3-ylmethyl]-3-methoxy-benzoic acid methylester (1.60 grams, 88% yield).
