Procedure

To a solution of N-[2-(1-acetyl-5-methoxyindolin-3-yl)ethyl]acetamide (0.29 mmol) in acetonitrile (1.5 ml) is added bis(trifluoroacetoxyiodobenzene) (PIFA 1.2 eq) and the medium is left stirring for 1 min at room temperature. Saturated sodium chloride solution (0.5 ml) is next added and, after 15 min, the mixture is diluted with dichloromethane (10 ml) and dried over magnesium sulphate. The crude product obtained after evaporation is chromatographed on a column of flash silica (5/95 methanol/dichloromethane) and N-[2-(1-acetyl-6-chloro-5-methoxyindolin-3-yl)ethyl]acetamide (70 mg) is thus obtained.
