    • A pyrimidine derivative of the formula :

      wherein
      R' is hydrogen, aryl optionally having substituent(s) selected from lower alkoxy, lower alkyl, halogen and lower
      +alkylthio or , in which N D is a N-containing heterocyclic group; R 2 is a) =N-R 2 or

      in which R 2 is aryl optionally substituted with lower alkyl, lower alkoxy, amino and/or acylamino and is hydrogen or lower alkyl, -N B is a N-containing heterocyclic group optionally substituted with acyl and/or ar(lower) alkyl; R 3 is hydrogen or lower alkyl; R 4 is a) imino optionally substituted with lower alkyl, aryl or ar(lower)alkyl, or b) lower alkyl, hydrogen, halogen, lower alkylthio, amino optionally substituted with lower alkyl, aryl, ar(lower)alkyl and/or acyl,
      or hydrazino optionally substituted with acyl, in which
      is a N-containing heterocyclic goup optionally substituted with acyl, and/or ar(lower)alkyl; R 5 is hydrogen, lower alkyl, lower alkanoyl optionally substituted with lower alkylamino or no significance; or R 3 and R 4 or R 4 and R 5 are taken together with the adjacent nitrogen atom and carbon atom to form a N-containing heterocyclic ring; R 6 is hydrogen, lower alkyl, halogen or aryl optionally having substituent(s) selected from lower alkoxy, lower alkyl, halogen and lower alkylthio substituents; the bond represents single bond or double bond; and the dotted line in the ring A represents one, two or three additional C-C and/or C-N bond(s) in the ring system, provided that R' and R 6 are not both hydrogen; and pharmaceutically acceptable salt thereof. These compounds are useful in the treatment of heart disease, hypertension, cerebrovascular disease and thrombosis. Processes for the preparation of these compounds are also described, together with novel starting compounds for use in such processes and pharmaceutical compositions comprising pyrimidine derivatives of the above formula.
