The invention relates to quinazoline derivatives, or pharmaceutically-acceptable salts thereof, which possess anti-tumour activity; to processes for their manufacture; and to pharmaceutical compositions containing them. The invention provides a quinazoline of the formula: ##STR1## wherein R.sup.1 includes hydrogen, amino and alkyl or alkoxy each of up to 4 carbon atoms; R.sup.2 includes hydrogen, alkyl, hydroxyalkyl and halogenoalkyl each of up to 4 carbon atoms; R.sup.3 is hydrogen or alkyl or up to 3 carbon atoms; Ar is phenylene or heterocyclene; L is a group of the formula --CO.NH--, --NH.CO--, --CO.NR.sup.4 --, --NR.sup.4.CO--, --CH.dbd.CH-- or --CO.O--, wherein R.sup.4 is alkyl of up to 4 carbon atoms; and Y is a branched alkyl group bearing substituents Y.sup.2 and Y.sup.3 the definition of each independently including hydroxy, cyano, aryl and heteroaryl, and the definition of Y.sup.3 also optionally including sulpho, N-phenylsulphonylcarbamoyl and 5-tetrazolyl; or a pharmaceutically-acceptable salt thereof.
