A series of difluorobenzothienoquinolines has been prepared by photocyclization of the appropriate carboxamides.The lactams obtained were converted into the corresponding chloro derivatives which were catalytically dechlorinated into the difluorobenzothienoquinolines.The latter compounds were transformed into the N-methyl quaternary salts.
