ChEBI: Indole-2-carboxylic acid is an indolyl carboxylic acid.

Indole-2-carboxylic acid is prepared by a two-step condensation–reductive cyclization route: starting from 1-methyl-2-nitrobenzene (1) and diethyl oxalate (2), the intermediate sodium salt of 3-(2-nitrophenyl)-2-oxopropanoic acid (3) is first obtained by condensation, which is then reduced and cyclized to give the target product indole-2-carboxylic acid (4) [1].
