Versuchsvorschrift

In chloroform (1.8 ml) was dissolved 4-(3-chloro-4-(3-fluorobenzyloxy)phenylamino)-6-(2-(N-(t-butoxycarbonyl)-N-ethylamino)ethyloxyimino)quinazoline (V-16, 54 mg), and trifluoroacetic acid (1.8 ml) was added, followed by stirring at room temperature for 1 hour. After completion of the reaction, the reaction mixture was concentrated, and diluted with ethyl acetate. The mixture was sequentially washed with aqueous saturated sodium bicarbonate solution, water, and aqueous sodium chlorite solution, and dried over magnesium sulfate. After concentration, the crystalline residue was washed with a mixture of dichloromethane-hexane (1:4) to obtain 4-(3-chloro-4-(3-fluorobenzyloxy)phenylamino)-6-(2-(N-ethylamino)ethyloxyimino)quinazoline (V-17, 28 mg) as a white solid.
