Versuchsvorschrift

A 6-benzyloxy-4-chloroquinoline derivative or a corresponding quinazolone derivative is reacted with a phenol derivative or a corresponding aniline derivative in a suitable solvent, for example, o-dichlorobenzene, or in the absence of a solvent, for example, at 120 to 180° C. (step (i) above). Next, a 6-hydroxyquinoline derivative may be produced by reacting the resultant compound with a suitable acid, for example, methanesulfonic acid/trifluoroacetic acid (step (ii) above). The contemplated compound may be produced by reacting the 6-hydroxyquinoline derivative with an alkylating agent, for example, 1-bromo-2-chloroethane (step (iii) above).
