Procedure

A mixture of 3 grams of mangenese dioxide and 3 grams of 5-fluoro-2,3-dihydro-1H-indole-6-sulfonic acid amide in 30 ml of dioxane was heated at 50° overnight. The reaction was filtered and the filtrate was evaporated to afford crude product which was purified on silica gel eluting with methylene chloride/ethyl acetate to give 1.1 grams of the titled compound. mp: 181-182° C.
