Process for the preparation of 2-hydrazono-propionic derivatives of the general formula I **(Formula)** in which R means a saturated or unsaturated straight-chain, branched or cyclic alkyl radical, and X means a valence line or a straight or branched chain saturated or unsaturated alkylene group with 1 to 4 carbon atoms, where in the case that X represents a valence line, R must not be any saturated cycloalkyl radical; and its physiologically harmless salts, esters and amides. |
