Herein is disclosed 2-(1-piperazinyl)-4-pyrimidinamine derivatives, acid addition salts thereof, processes for their preparation, methods of using the derivatives and pharmaceutical compositions of the derivatives. The derivatives are distinguished most readily by having novel substituents at position 4 of the piperazinyl radical, the substituents being selected from the group consisting of optionally substituted 2-cycloheptimidazolyl, 1,4,5,6,7,8-hexahydrocycloheptimidazol-2-yl, 2-benzoxazolyl, benzthiazol-2-yl, 1H-2-benzimidazolyl and 1-oxo-2,4,6-cycloheptarien-2-yl. The derivatives are useful for treating hypertension in a mammal. |
