Decarbomethoxylation of the known 3-hydroxyindole-2-carboxylate (I) in the presence of magnesium chloride in NMP at 160 C afforded indolinone (II), which was subsequently reduced with NaBH4 to the 3-hydroxy indoline (III). Dehydration of (III) by means of trifluoroacetic acid furnished indole (IV).
