Reaction Steps

In N,N-dimethylacetamide (1.5 ml) were dissolved 4-(3-chloro-4-(3-fluorobenzyloxy)phenylamino)-6-(hydroxyimino)quinazoline (V-2, 84 mg) and N-(4-bromobutyl)-N-(2-methanesulfonylethyl)-2,2,2-trifluoroacetamide (71 mg), and potassium carbonate (41 mg) was added, followed by stirring at 60° C. for 1.3 hours with heating. Thereafter, the reaction mixture was poured into 0.5 M citric acid, followed by extraction with ethyl acetate. The organic layer was washed with water and aqueous sodium chloride solution, and dried over magnesium sulfate. The crude product was purified by silica gel chromatography (eluting with hexane:ethyl acetate=1:4) to obtain 4-(3-chloro-4-(3-fluorobenzyloxy)phenylamino)-6-(4-(N-(2-(methanesulfonyl)ethyl)-2,2,2-trifluoroacetamido)butyloxyimino)quinazoline (V-14, 41 mg) as a pale yellow solid.
