Procedure

550 mg (1.07 mmol) of 2,2,2-trifluoro-N-{3-fluoro-4-[(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-4-yl)methyl]phenyl}acetamide and 143 mg (1.07 mmol) of N-chlorosuccinimide in 23 ml of carbon tetrachloride are heated at reflux for 20 min. After cooling, the mixture is diluted with water in dichloromethane and extracted. The organic phase is separated off, dried over magnesium sulfate and concentrated under reduced pressure. The residue is purified by column chromatography on silica gel (mobile phase: dichloromethane with increasing amounts of methanol).
