New pyrimidine derivatives of the formula: ##STR1## wherein Z is a group selected from ##STR2## in which R.sup.1 and R.sup.2 are each hydrogen, alkenyl, ar(lower)alkyl or lower alkyl optionally substituted with epoxy, hydroxy, amino and/or lower alkylamino and R.sup.5 is lower alkyl, R.sup.3 is hydrogen, aryl optionally substituted with lower alkyl, lower alkoxy and/or halogen, or pyridyl optionally substituted with lower alkyl, R.sup.4 is hydrogen, lower alkyl or phenyl optionally substituted with lower alkoxy, and Y is.dbd.O, .dbd.S or .dbd.N--R.sup.6, in which R.sup.6 is lower alkyl; cyclo(lower)alkyl; ar(lower)alkyl optionally substituted with lower alkoxy; N-containing unsaturated heterocyclic group optionally substituted with lower alkyl; or aryl optionally substituted with hydroxy, lower alkyl, halogen or lower alkoxy, in which lower alkoxy substituent may be substituted with epoxy, hydroxy, amino and/or lower alkylamino, provided that Y is.dbd.N--R.sup.6 when R.sup.3 and R.sup.4 are each hydrogen, and Y is.dbd.S or.dbd.N--R.sup.6 when R.sup.1 and R.sup.2 are each hydrogen or lower alkyl and R.sup.3 is phenyl, and pharmaceutically acceptable salts thereof, and processes for preparation thereof and pharmaceutical composition comprising the same. These derivatives and salts thereof are useful as cardiotonic, antihypertensive agent, cerebrovascular vasodilator and anti-platelet agent.
