Participants

Reaction Steps

4 g 6-nitro-1H-indole are added batchwise at 0° C. to 800 mg sodium hydride (60% in mineral oil) in 20 mg dimethylformamide. The mixture is stirred for 10 minutes, then 1.86 ml methyl iodide are added dropwise and the mixture is left overnight to come up to ambient temperature. Then it is divided between water and ethyl acetate, the aqueous phase is extracted with ethyl acetate and the combined organic phases are washed with saturated sodium chloride solution. After drying with magnesium sulphate the solvents are eliminated in vacuo.
