Pyrimidine derivatives of the formula:
wherein
Ar is aryl group substituted with 1 to 3 substituent(s) selected from the group consisting of nitro, halo(lower)alkyl, lower alkoxy and a group of the formula:
(in which l, R4, R5 and R6 are each as defined in the below);
R1 is esterified carboxy group, lower alkanoyl group, hydroxy(lower)alkyl group or a group selected from the following formulas:
(in which R7. R8, and A are each as defined in the below);
R2 is hydrogen, lower alkyl group or a group of the formula:
(in which B, R7 and R8 are each as defined in the below);
R3 is lower alkyl group or aryl group;
ℓ is an integer of 0, 1 to 6; R4, R5 and R6 are each hydrogen or halogen; R7 and R8 are each hydrogen, optionally substituted N-containing heterocyclic group or lower alkyl group optionally substituted with 1 to 3 substituent(s) selected from the group consisting of mono- or di-(lower)alkylamino, and optionally substituted N-containing heterocyclic group; or
R7 and R8 are taken together to form an optionally substituted N-containing heterocyclic group with the adjacent nitrogen atom;
A and B are each straight or branched lower alkylene group which may be substituted with a lower alkylidene; provided that R1 is a group of the formula :
(in which R', R8 and A are each as defined above) when R2 is hydrogen or lower alkyl group; and their pharmaceutically acceptable salts. Processes for the preparation of these pyrimidine derivatives are also described, together with pharmaceutical compositions comprising them.
The compounds are useful in the treatment of cerebrovascular diseases.
