New liquid-crystalline 2-(4-alkylphenyl)-5-alkylpyridines were synthesized by the reaction of 2-(4-alkylphenyl)-1-lithio-1,2-dihydropyridines with alkyl bromides.The compounds obtained have relatively low melting points and narrow temperature ranges of the existence of a nematic meso phase; the thermal stability of the meso phase is determined by the lenght of the alkyl group in the pyridine and benzene parts of the molecule.
