Abstract
Process for the preparation of cysteine derivatives in particular of cysteine ester hydrochlorides and especially those new cysteine esters corresponding to the formula wherein r designates an aliphatic hydrocarbon radical having one or at least three carbon atoms and which can be carried by a heterocyclic radical as a substituent, characterized in that the direct esterification of the corresponding cysteine salt is effected by means of an excess of the chosen alcohol in the presence of acid identical to that of cysteine.
