Reaction Steps
A suspension of 5-chlorosulfonyl-2-oxindole (5 g), 3-chloroaniline (2.74 mL) and pyridine (3.5 mL) in dichloromethane (30 mL) was stirred at room temperature for overnight. The precipitate was filtered, washed with dichloromethane and dried to give 5.2 g (74%) 2-oxo-2,3-dihydro-1H-indole-5-sulfonic acid (3-chloro-phenyl)-amide.
