This invention concerns compounds of formula (I) ##STR1## where A is a C.sub.1 or C.sub.2 alkylene chain optionally substituted by lower alkyl; Z is a bicyclic oxygen-containing aryl radical (e.g. 2,3-dihydro-1,4-benzodioxin-5-yl); R is hydrogen or lower alkyl; R.sup.1 is aryl or aryl(lower)alkyl; R.sup.2 is hydrogen or lower alkyl; and R.sup.3 is hydrogen, an alkyl group of 1 to 10 carbon atoms, cycloalkyl of 3 to 12 carbon atoms; cycloalkyl(lower)alkyl, aryl or aryl(lower)alkyl or R.sup.2 and R.sup.3 together with the nitrogen atom to which they are both attached represent a saturated heterocyclic ring which may contain a further hetero atom, and the pharmaceutically acceptable acid addition salts thereof. The compounds are 5-HT.sub.1A -antagonists which may be used, for example, in treating anxiety.
这项发明涉及式(I)的化合物 ##STR1## 其中A是一个C.sub.1或C.sub.2烷基链,可选择地被较低烷基取代;Z是一个含氧的双环芳基基团(例如2,3-二氢-1,4-苯并二氧杂环戊烯基);R是氢或较低烷基;R.sup.1是芳基或芳基(较低)烷基;R.sup.2是氢或较低烷基;R.sup.3是氢,1至10个碳原子的烷基基团,3至12个碳原子的环烷基,环烷基(较低)烷基,芳基或芳基(较低)烷基,或R.sup.2和R.sup.3与它们都连接的氮原子一起代表一个饱和杂环环,该环可能含有进一步的杂原子,以及其药学上可接受的酸盐。这些化合物是5-HT.sub.1A-拮抗剂,例如可用于治疗焦虑。
