Benzo-heterocyclic compounds of the formula: ##STR1## wherein R.sup.1 is a lower alkyl group; R.sup.2 is a halogen atom or a group of the formula ##STR2## (wherein R.sup.4 and R.sup.5 combine together with the nitrogen atom to which they bind to form a 5- or 6-membered saturated heterocyclic group which may optionally contain an oxygen atom or nitrogen atom within the ring as an additional hetero atom and may also optionally have a substituent selected from a lower alkyl or hydroxy group on the hetero ring); R.sup.3 is an amino or nitro group; X is a halogen atom; and n is an integer of 1 or 2, and a salt thereof, which have excellent antimicrobial activities and are useful as an antimicrobial agent, or as an intermediate for the preparation of an active compound.
公式为:##STR1## 其中 R.sup.1 是较低的烷基基团; R.sup.2 是卤素原子或公式 ##STR2## 的基团(其中 R.sup.4 和 R.sup.5 与它们结合的氮原子结合形成一个5-或6-成员饱和杂环基团,该基团可以在环内包含一个氧原子或氮原子作为额外的杂原子,并且还可以在杂环上具有从较低的烷基或羟基群中选择的取代基); R.sup.3 是氨基或硝基基团; X 是卤素原子; n 是1或2的整数,以及其盐,具有优异的抗微生物活性,可用作抗微生物剂或用作活性化合物的制备中间体。
