Reaction Steps

Add to a solution of 2-ethyl-3-iodo-6-nitro-1H-indole (0.30 g, 00.95 mmol) in anhydrous DMF (5 mL) sodium hexamethyldisilylamide (1.0M in THF, 1.0 mL, 1.00 mmol) dropwise followed by ethyl iodide (0.23 mL, 2.85 mmol) and stir 3 hours at ambient temperature. Quench the reaction with 1N HCl and add ethyl acetate. Wash the organic layer 2×1N HCl, 1× brine. Dry the organic layer over sodium sulfate, concentrate in vacuo, and flash chromatograph with 20% ethyl acetate hexane to afford 0.28 g (86%) of the title compound.
