A method has been developed for the one pot synthesis of 1′-alkyl-1′,4′-dihydro-2.3′-biquinolyl-4′-thiones based on the reduction of 1-alkyl-3-(2-quinolyl)quinolinium halides with sodium borohydride and subsequent thiolation. 1′-Alkyl-1′,4′-dihydro- 2,3′-

Thiolation of 1-alkyl-3-(2-quinolyl)quinolinium halides by a mixture of sulfur with KOH in DMF leads to formation of 1′-alkyl-1′,4′- dihydro-2,3′-biquinolyl-4′-thiones, rearrangement of which in boiling ethylene glycol makes it possible to obtain 4′-alkylthio-2,3′-biquinolyls.
