Versuchsvorschrift
3-Chlorobenzenesulphonyl chloride (71 mg, 0.3 mmol, 1.1 equiv.) was added to a mixture of crude 2-chloro-4-[(2,3-dihydro-1H-indole-6-carbonyl)-amino]-benzoic acid methyl ester (100 mg, 0.3 mmol, 1 equiv.) and pyridine (0.2 mL, 2.4 mmol, 8 equiv.) in dichloromethane (2 ml) and the mixture was stirred at room temperature for 16 hours. The solvent was removed under a stream of N2 and the residue purified by column chromatography (SiO2, dichloromethane). The fractions were combined to afford crude 2-chloro-4-{[1-(3-chloro-benzenesulfonyl)-2,3-dihydro-1H-indole-6-carbonyl]-amino}-benzoic acid methyl ester, 101 mg. This material was taken onto the next step without further purification. LC @215 nm; Rt 2.52: 84%, m/z (ES+): 505 (M+H+.).
