    摘要: The invention concerns quinazoline derivatives of the formula I ##STR1## wherein n is 1, 2 or 3 and each R.sup.2 is independently halogeno, trifluoromethyl or (1-4C)alkyl; R.sup.3 is (1-4C)alkoxy; and R.sup.1 is di-�(1-4C)alkyl!amino-(2-4C)alkoxy, pyrrolidin-1-yl-(2-4C)alkoxy, piperidino-(2-4C)alkoxy, morpholino-(2-4C)alkoxy, piperazin-1-yl-(2-4C)alkoxy, 4-(1-4C)alkylpiperazin-1-yl-(2-4C)alkoxy, imidazol-1-yl-(2-4C)alkoxy, di-�(1-4C)alkoxy-(2-4C)alkyl!amino-(2-4C)alkoxy, thiamorpholino-(2-4C)alkoxy, 1-oxothiamorpholino-(2-4C)alkoxy or 1,1-dioxothiamorpholino-(2-4C)alkoxy, and wherein any of the above-mentioned R.sup.1 substituents comprising a CH.sub.2 (methylene) group which is not attached to a N or O atom optionally bears on said CH.sub.2 group a hydroxy substituent; or pharmaceutically-acceptable salts thereof; processes for their preparation, pharmaceutical compositions containing them, and the use of the receptor tyrosine kinase inhibitory properties of the compounds in the treatment of proliferative disease such as cancer.
