Synthesis and utilization of a simple copper on iron catalyst in the coupling of aryl halides with thiols through disulfide intermediate is reported. The iron support of copper catalyst ensures reductive media for the coupling, allows easy removal of the metals by outer magnetic field and enables the recycling of the catalyst.

Disclosed is an efficient and widely-applicable method for commercially producing a thioether compound or a thiol compound which is useful as a pharmaceutical product or a production intermediate of a pharmaceutical product. Specifically disclosed is a method for producing a thioether compound represented by the general formula [I] below or a salt thereof. This method is characterized in that a compound represented by the following general formula [III]: [III] (wherein X represents a bromine atom, a chlorine atom or a trifluoromethylsulfonyloxy group, and ring A represents an aryl group or a heteroaryl ring group) or a salt thereof is reacted with a thiol compound represented by the following general formula [II]: [II] or a salt thereof in the presence of a palladium compound such as Pd2(dba)3, a base such as i-Pr2NEt and a phosphorus compound represented by the following formula [AA].

One aspect of the invention relates to substitute quinolines with antimalarial activity, and compositions and kits comprising at least one of them. Another aspect of the invention relates to methods for the treatment or prevention or both of malaria comprising administering to a subject a therapeutically effective amount of such a compound. Importantly, a number of the compounds show excellent potency against both chloroquine-sensitive and chloroquine-resistant strains.
