as alkoxy quinolines were halogenated at the C5-position via remote functionalization for the first time. This methodology provides a highly economical route to halogenatedquinolines with excellent functional group tolerance, thus providing a good complement to existing remote functionalization methods of quinolin-8-amide derivatives and broadening the field of remote functionalization. The utility

The C(5)H and C(6)H methoxylation of quinoline amides with methanol was presented by using PtCl2 or triethylamine as an additive. The reaction when conducted under mild conditions provides expedient access to quinoline derivatives, which are frequently found in many drug candidates.
