The preparation involved a straightforward reaction sequence with high yields (overall 48-56% in three or four steps). The commercially available 5-bromo-7-nitroindoline (16) was reacted with the 4-methoxybenzenesulfonyl chloride in pyridine to afford the 5-bromo-1-(4-methoxybenzenesulfonyl)-7-nitroindoline (17).
