Oxadiazolo[2,3-c]pyrimidine derivatives of the formula ##STR1## wherein R is alkyl, alkenyl, alkynyl or alkoxyalkyl, as well as their salts, are described. The compounds of formula I have valuable, long-lasting vasodilating and/or blood pressure-lowering properties and are useful for the treatment of vascular-conditioned hypertensions or as vasodilators in peripheral blood supply disorders. The compounds are prepared, inter alia, by carbamoylating the corresponding derivative containing a free amino group and optional salt formation.
