Participants

Reaction Steps

Acetic anhydride (0.5 ml) is added with stirring to N-[2-(5-methoxy-2-oxo-2,3-dihydroindol-3-yl)ethyl]acetamide (120 mg) dissolved in benzene (5 ml). The mixture is heated for 1 h in refluxing benzene. The solvent is evaporated off and the crude product is separated on a silica plate. N-[2-(1-acetyl-2-oxo-5-methoxyindol-3-yl)ethyl]acetamide (6) is thus obtained.
