A process for producing a phenyllactic acid derivative comprises hydrogenating a phenylpyruvic acid derivative in the presence of a catalyst containing at least one element selected from the Group VIII elements of the periodic table. The process provides a phenyllactic acid derivative useful as an intermediate in the production of pharmaceuticals and agricultural chemicals. The process uses as a starting material a phenylpyruvic acid derivative which is easily synthesized. The process is simpler in operation and provides a higher yield than conventional processes.
