Article abstract of DOI:10.1055/s-1986-31795

Chlorination of 2-, 3-, or 4-alkylthioquinolines (or -pyridines) with N-chlorosuccinimide or sulfuryl chloride affords 2-, 3-, or 4-(1-chloroalkylthio)-quinolines (or -pyridines), respetively, which in the case of ethyl or propyl compounds can be dehydrochlorinated to 1-alkenylthio derivatives. 4-Chloro-3-(1-chloroalkylthio)-quinolines react with thiourea to give 2-alkyl-1,3-dithiolo<4,5-c>quinolines.
