Pyrrolotriazolopyrimidine derivatives having the formula ##STR1## wherein R.sup.1 represents hydrogen atom or an alkyl group having from 1 to 4 carbon atoms and R.sup.2 represents an alkyl group having from 1 to 4 carbon atoms, a cycloalkyl group having from 5 to 8 carbon atoms, a phenyl group optionally substituted with one or more halogen atoms or a phenylalkyl group having the formula ##STR2## IN WHICH R.sup.3 represents hydrogen atom or an alkyl group having from 1 to 4 carbon atoms, R.sup.4 represents halogen atom, an alkyl group having from 1 to 4 carbon atoms or an alkoxy group having from 1 to 4 carbon atoms, m represents an integer from 0 to 2 and n represents an integer from 0 to 3, and pharmacologically acceptable salts thereof. The compounds are useful as vasodilating or hypotensive agents and may be prepared by reacting triazolopyrimidine derivatives having the formula ##STR3## wherein X.sup.1 and X.sup.2 may be the same or different and each represents a halogen atom and R.sup.1 has the same meaning as defined above with an amine having the formula R.sup.2 - NH.sub.2 wherein R.sup.2 has the same meaning as defined above.
吡咯并三唑并嘧啶衍生物,具有式##STR1##其中R1代表氢原子或具有1至4个碳原子的烷基,R2代表具有1至4个碳原子的烷基,具有5至8个碳原子的环烷基,可任选地被一个或多个卤素原子取代的苯基,或具有式##STR2##的苯基烷基,其中R3代表氢原子或具有1至4个碳原子的烷基,R4代表卤素原子,具有1至4个碳原子的烷基或具有1至4个碳原子的烷氧基,m代表0至2的整数,n代表0至3的整数,以及药理学上可接受的盐。这些化合物作为血管扩张剂或降压剂有用,并可通过使具有式##STR3##的三唑并嘧啶衍生物与具有式R2-NH2的胺反应制备,其中X1和X2可以相同或不同,各代表卤素原子,R1具有如上定义的相同含义,R2具有如上定义的相同含义。
