Procedure
To a solution of 1-benzenesulfonyl-7-methoxy-4-nitro-1H-indole (R) (1 eq) in methanol was added a solution of sodium hydroxide (5 eq) in water. The solution was heated to reflux for 3 hrs. Methanol was removed under reduced pressure then water and ethyl acetate were added. The ethyl acetate layer separated and washed repeatedly (3×) with water. The ethyl acetate layer was concentrated and evaporated to dryness to produce the desired product.
