1. Pyrimidine derivatives of the formula :
wherein
Ar is aryl substituted with 1 to 3 substituent(s) selected from the group consisting of nitro, amino, halogen, cyano, hydroxy, carbamoyl, halo(lower)-alkyl, lower alkoxy, halo-(iower) alkoxy, lower alkanoyloxy, lower alkylthio, lower alkanesulfinyl, lower alkanesulfonyl, esterified carboxy, optionally substituted N-containing heterocyclic group and a group of the formula :
(in which X, ℓ, R4, R5 and R6 are each as defined in the below) or heterocyclic group containing one nitrogen and/or sulfur atom(s) and optionally substituted with nitro or halogen substituent(s);
R1 is carboxy, esterified carboxy, lower alkanoyl, cyano, amino, carboxyamino, esterified carboxyamino, a group of the formula :
R7 and R8 are taken together to form an optionally substituted N-containing heterocyclic group with the adjacent nitrogen atom; provided that the substituent(s) on the aryl group for Ar is not halogen when R2 is hydrogen; and the pharmaceutically acceptable salts thereof.
The pyrimidine derivatives disclosed are useful in the treatment of cerbrovascular diseases.
