Abstract
Procedure for obtaining chloramphenicol ester salts of the general formula **(See formula)** in which R1 is hydrogen or: **(See formula)** and R2 is: **(See formula)** HX is an organic or inorganic acid or an N-acetylamino acid, characterized by reacting racemic L-β-phenylalanine or β-phenylalanine substituted by a protective L group removable by hydrolysis with chloramphenicol in the presence of a condensing agent separating the isomers resulting when the racemic is used and then removing the N-protecting group from the ester thus obtained.
