The action of sodium methanethiolate (in boiling DMF) on x,y-dichloroquinolines (1) (x=3 or 6, y=2 or 4) occured via chlorine ipso-substitution followed by methanethiolato-S-demthylation to yield x,y-quinolinedithiolates 2A which were: i) subjected to S-methylation, ii) oxidatively chlorinated to y,y'-bis(x-chloro-x-quinolinesulfonyl chlorides (5). Oxidative chlorination of y,y'-bis(x-chloro quinolinyl) disulfides (7) led to x-chloro-y-quinolinesulfonyl chlorides (8) accompanied by x,y-dichloroquinolines (1). Both quinolinessulfonyl chlorides 5 and 8 were efficiently converted to the corresponding quinolinesulfonamides 6 and 9.

Chlorinolysis of 4-chloro-3-benzylthioquinoline (2) or thioquinanthrene (1) using chlorine gas in the presence of water gave 4-chloro-3-quinolinesulfonyl chloride (3). Amination of (3) performed in ether led to 4-chloro-3-quinolinesulfonamides (4). Reactions of compound (3) with an excess of primary or secondary amine in two phase (water/toluene or benzene) system gave 4-(substituted amino)-3-quinolinesulfonamides (5) with two identical amine rests. While 4-chloro-3-quinolinesulfonamides (4) were aminated with an excess of amine into aminosulfonamides (5) with two identical or two various amine rests.
