A compound which is a pyrimidine-4-carboxamide derivative of the general formula (I) ##STR1## in which n is 0 or 1, m is 0 or 1, R.sub.1 represents a methyl group when R.sub.2 represents a phenoxy(C.sub.1 -C.sub.4)alkyl group (in which the phenoxy group optionally carries 1 or 2 substituents selected from halogen atoms and methoxy groups), or R.sub.1 and R.sub.2 form together with the nitrogen atom to which they are attached a 4-phenoxypiperidin-1-yl group (in which the phenoxy group optionally carries 1 or 2 substituents selected from halogen atoms and methoxy groups), a phenoxymethylpiperidin-1-yl group (in which the phenoxy group optionally carries 1 or 2 C.sub.1 -C.sub.4 alkyl groups) or a 4-phenylpiperazin-1-yl group (in which the phenyl group optionally carries 1 or 2 substituents selected from halogen atoms and methoxy groups), and R.sub.3 represents a hydrogen atom or only when n is 1 a hydroxyl group or a methoxy group, or is an addition salt thereof with an acid, is useful as an .alpha.-adrenergic antagonist.
化合物是一种通式(I)的嘧啶-4-羧酰胺衍生物,其中n为0或1,m为0或1,当R.sub.2表示苯氧基(C.sub.1-C.sub.4)烷基(其中苯氧基可选地携带1或2个卤素原子和甲氧基)时,R.sub.1表示甲基基团,或者R.sub.1和R.sub.2与它们连接的氮原子一起形成4-苯氧基哌啶-1-基基团(其中苯氧基可选地携带1或2个卤素原子和甲氧基),苯氧甲基哌啶-1-基基团(其中苯氧基可选地携带1或2个C.sub.1-C.sub.4烷基)或4-苯基哌嗪-1-基基团(其中苯基可选地携带1或2个卤素原子和甲氧基),且R.sub.3表示氢原子或仅当n为1时,表示羟基或甲氧基,或其与酸的加成盐在α-肾上腺素受体拮抗剂方面有用。
