The alkaline hydrolysis of 5-methoxyisatin (I) provides the ortho-(aminophenyl)glyoxylic acid salt (II), which is then alkylated by 2-bromoacetophenone (III) to furnish the N-phenacylisatin (IV). Rearrangement of (IV) in the presence of NaOH gives rise to a 40:60 mixture of the indolecarboxylic acid (V) and the target decarboxylated compound.
