Abstract

There are described new pyrimidine derivatives of the general formula I ##STR1## in which n is 0, 1 or 2; PA0 R.sub.1 is PA1 (a) the group --CXR.sub.5, where X is oxygen or sulphur and R.sub.5 is hydrogen, a nitrogen or sulphur containing heterocyclic group, which can contain other hetero atoms, optionally substituted alkenyl, acyl, alkoxycarbonyl, alkyl substituted by aryloxy, or optionally substituted mono- or dialkylamino; or R.sub.5 is the group --NHR.sub.6, where R.sub.6 is substituted amino, substituted carbamoyl, optionally substituted alkylsulphonyl, acyl or arylsulphonyl, and when n is 0 or when X is sulphur, R.sub.5 can also be alkyl, haloalkyl, aryl, aralkyl, alkoxycarbonylalkyl or arylamino; PA1 (b) cyano or the group --CXYR.sub.7, where X and Y are the same or different and are oxygen, sulphur or optionally substituted imino and R.sub.7 is optionally substituted alkyl, aryl, acyl or a nitrogen or sulphur containing heterocyclic group, which can contain other hetero atoms; or PA1 (c) when n is 1 or 2 and at least one R.sub.4 group is haloalkoxy, R.sub.1 can be hydrogen; PA0 R.sub.2 and R.sub.3 are the same or different and are alkyl, and PA0 R.sub.4 is alkyl, alkoxy, ha…
