FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing beta-mimetics of formula 
, where values of n, R1, R2, R3 are given in the claim, which can be used in medicine. The method is realised by reacting a compound of formula 1a with a compound of formula 1b in toluene for 3-9 hours to obtain a compound of formula 1c. The compound of formula 1 is then obtained by splitting the protective group from the compound of formula 1c.
EFFECT: improved method of producing beta-mimetics.
