Compounds corresponding to the general formula (I) ##STR1## in which n represents 0 or 1, R.sub.1 represents a methyl group, in which case R.sub.2 represents a phenoxy(C.sub.1 -C.sub.4)alkyl group (in which the phenoxy group is optionally substituted), or else R.sub.1 and R.sub.2 together form, and with the nitrogen atom which carries them, a 4-(phenoxymethyl)piperid-1-yl group (in which the phenoxy group is optionally substituted) or a 4-phenylpiperazin-1-yl group (in which the phenyl group is optionally substituted), R.sub.3 represents a hydrogen atom or a methyl group, R.sub.4 represents a hydrogen atom and R.sub.5 represents a hydrogen atom or a group of general formula -CH.sub.2 -CH.sub.2 -NH-R.sub.6, R.sub.6 being a hydrogen atom or a tert-butyloxycarbonyl, 4-carbamoylpyrimidin-2-yl or 5-carbamoylpyrazin-2-yl group, are useful in the treatment of diseases and complaints involving hyperactivity of the .alpha.-adrenergic system at the level of the lower urinary apparatus.
与一般式(I)##STR1## 对应的化合物,其中n代表0或1,R.sub.1代表一个甲基基团,此时R.sub.2代表一个苯氧基(C.sub.1 -C.sub.4)烷基基团(其中苯氧基团可选择地被取代),或者R.sub.1和R.sub.2一起形成,并与携带它们的氮原子一起形成4-(苯氧甲基)哌啶-1-基基团(其中苯氧基可选择地被取代)或4-苯基哌嗪-1-基基团(其中苯基可选择地被取代),R.sub.3代表一个氢原子或一个甲基基团,R.sub.4代表一个氢原子,R.sub.5代表一个氢原子或一个一般式-CH.sub.2 -CH.sub.2 -NH-R.sub.6的基团,其中R.sub.6是一个氢原子或一个叔丁氧羰基、4-羰基嘧啶-2-基或5-羰基吡嗪-2-基团,对于治疗涉及下尿道处α-肾上腺素系统过度活跃的疾病和症状是有用的。
