The synthetic route is as follows.
Preparation of 5-nitro-oxindole To a solution of oxindole (26 g) in 100 mL of concentrated sulfuric acid at -15 C. was added fuming nitric acid (8.4 mL) dropwise. Careful attention was paid to maintain the reaction temperature at -15 C. After the addition was complete, the reaction was stirred for 30 minutes and then poured into ice water. A yellow precipitate was formed which was isolated by filtration to provide 34 grams (98%) of 5-nitro oxindole.
