Reaction Steps

Alternatively, the 4-(aminophenoxy)quinoline derivative or corresponding quinazoline derivative can be produced by reacting an aminophenol derivative with the 4-chloroquinoline derivative or corresponding quinazoline derivative in a suitable solvent, for example, dimethyl sulfoxide, in the presence of a base, for example, sodium hydride. Alternatively, the 4-(aminophenoxy)quinazoline derivative can also be produced by dissolving an aminophenol derivative in an aqueous sodium hydroxide solution and subjecting the solution to a two-phase reaction with a solution of the 4-chloroquinazoline derivative in a suitable organic solvent, for example, ethyl methyl ketone, in the presence of a phase transfer catalyst, for example, tetra-n-butylammonium chloride, or in the absence of the catalyst.
