CARBAMIC ACID DERIVATIVES AND THEIR PHARMACEUTICALLY ACCEPTABLE ACID-ADDITIVE SALTS, METHOD OF THEIR SYNTHESIS (VARIANTS) AND PHARMACEUTICAL COMPOSITION

摘要

FIELD: organic chemistry. SUBSTANCE: invention proposes derivatives of carbamic acid of the general formula (I): where R means group of the general formula (II) or (III) where R - phenyl(lower)alkyl; R - phenyl(lower)alkyl or hydrogen atom; R - hydrogen atom; R means group of the general formula (IV) or (V) where X - hydrogen atom and R7,R8,R9,R and R means lower alkyl, and pharmaceutically acceptable acid-additive salts, and a method of their synthesis. The synthesized compounds can be used in medicine, in part, in neurology (for Alzheimer disease treatment). EFFECT: improved method of synthesis. 10 cl, 1 tbl
