A process for the production of indolyl lactic acid which includes heating an aqueous solution of 2,3-dihydro-2,5-furan dicarboxylic acid to boiling. The aqueous solution is cooled and reacted with phenyl hydrazine or a salt of phenyl hydrazine. The resultant phenylhydrazone is converted by heating with sulfuric acid to indolyl lactic acid.
