FIELD: organic synthesis.
SUBSTANCE: invention relates to improved method of preparing title compounds depicted by general formula: 
, wherein R1 = R2 = H : R = N(CH3)2, OCH3, C(CH3)3; R1 = H, R2 = CH3 : R = N(CH3)2, C(CH3)3; R1 = R2 = CH3 : R = N(CH3)2, which are intermediates in synthesis of biologically active products, via reaction of 1,3-dehydroadamantane or homologues thereof with benzene derivatives selected from series: N,N-dimethylaniline, anisole, and tert-butylbenzene at molar ratio of reactants1:(5-6), respectively, in a benzene derivative at 120-130°C for 5-6 h.
EFFECT: expanded synthetic possibilities.
