Versuchsvorschrift

Water (4.5 ml), potassium carbonate (25.9 g, 187 mmol) and ethyl bromoacetate (20.8 ml, 188 mmol) were added sequentially to a suspension of 2-methyl-4-nitro-1H-indole (30 g, 170 mmol) in acetonitrile (225 ml) and the mixture heated at 60° C. for 16 hours. After allowing to cool to ambient temperature, water (225 ml) was added and the resulting mixture was broken up and then filtered. The solid was washed with water (2×75 ml), followed by IMS (2×75 ml) then dried in a vacuum oven to give (4-nitro-2-methyl-1H-indol-1-yl)-acetic acid, ethyl ester, 32.15 g (72%).
