FIELD: chemistry.
SUBSTANCE: invention relates to novel compounds - pharmaceutically acceptable salts of (S)-N-[4-(1-adamantyl)benzoyl]-α-amino acids of general formula (1) 
, where A+ denotes an ion of an alkali metal, ammonia and N+(C1-4alkyl)4, R2 provided that R1 denotes a hydrogen atom, radicals -CH3, -CH(CH3)2, -CH2CH(CH3)2, -CH(CH3)CH2CH3, CH2-CH2-SH, -CH2-CH2-S-CH3, 
R1 and R2 together denote a biradical -CH2-CH2-CH2-, closed in the pyrrolidine ring, as well as a method of producing said compounds.
EFFECT: improved method of producing the said compounds.
