Reaction Steps

To a solution of 7-chloro-5-nitroindoline (0.23 g, 1.2 mmol) in 20 mL of acetone was added 2,3-dichloro-5,6-dicyano-1,4-benzoquinone until color of the solution turns to dark green. Reaction mixture was concentrated in vacuo providing a dark residue which was subjected to column chromatography (CHCl3, neat) to yield 0.18 g (0.94 mmol, 79%) of the indole.
