FIELD: medicine, pharmaceutics.
SUBSTANCE: invention concerns chemistry of adamantane derivatives, namely to a new method of obtaining of dialkylamides of 3-brome-1-adamantilalkancarbon acids of the general formula: 
R1,R2=H:R3=N(C2H5)2
R1, R2=CH3:R3=N(C2H5)2
which can be of interest as semiproducts in synthesis of some biologically active substances possessing antiviral activity. Method lies in interaction of 1,3-dehydroadamantane with dialkylamides of α-bromalkancarbon acids from the row: diethylamide of α-bromacetic acid, piperidide of α-brompropionic acid, diethylamide of α-bromo-isobutyric acid at mole ratio of reagents peer accordingly 1:3-4, in the environment of the initial dialkylamides of α-bromalkancarbon acids, at temperature of 80-90°C within 4-6 hours.
EFFECT: obtaining of bonds of declared structural formula, excluding reception stage adamantilealkanecarbon acids.
