Phenylpiperazine derivatives having the general formula (I) ##STR1## in which R.sub.1 represents a radical S(O).sub.m R.sub.3, S(O).sub.n CF.sub.3 or ##STR2## in which radicals m is 0, 1 or 2, n is 1 or 2, R.sub.3 is an alkyl radical having 1 to 10 carbon atoms and R.sub.4 and R.sub.5 independently represent a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms, or the N atom, R.sub.4 and R.sub.5 together form a heterocyclic ring, which can contain another hetero-atom, and R.sub.2 represents a hydrogen atom, the radical CH.sub.2 --CH.sub.2 --OH or a radical of formula CH.sub.2 --CH.sub.2 --O--COR.sub.6, CH.sub.2 --CH.sub.2 --O--CONHR.sub.6 or CH.sub.2 --CH.sub.2 --O--R.sub.6 in which radicals R.sub.6 being an alkyl radical having 1 to 6 carbon atoms and their pharmaceutically acceptable acid addition salts are useful psychotropic agents and analgesics. Compounds in which R.sub.1 is --SCH.sub.3 and simultaneously R.sub.2 is H are not part of the invention. These derivatives can be prepared by reacting an aniline derivative of formula ##STR3## with a compound of formula ##STR4## in which X represents a halogen atom or OH, alkyl--SO.sub.3 or aryl--SO.sub.3 group or the two X symbols together represent a divalent oxygen atom, thereby completing a morpholine ring.
具有一般式(I)的苯基哌嗪衍生物 ##STR1##
其中R.sub.1表示基团S(O).sub.m R.sub.3,S(O).sub.n CF.sub.3或##STR2##
其中基团m为0、1或2,n为1或2,R.sub.3为具有1至10个碳原子的烷基基团,而R.sub.4和R.sub.5分别表示氢原子或具有1至4个碳原子的烷基基团,或N原子,R.sub.4和R.sub.5在一起形成一个杂环环,可以含有另一个杂原子,而R.sub.2表示氢原子,基团CH.sub.2 --CH.sub.2 --OH或式子CH.sub.2 --CH.sub.2 --O--COR.sub.6,CH.sub.2 --CH.sub.2 --O--CONHR.sub.6或CH.sub.2 --CH.sub.2 --O--R.sub.6的基团,其中基团R.sub.6为具有1至6个碳原子的烷基基团,它们的药学上可接受的酸盐是有用的精神药物和镇痛剂。其中R.sub.1为--SCH.sub.3且同时R.sub.2为H的化合物不属于本发明。这些衍生物可以通过将式子 ##STR3##的苯胺衍生物与式子 ##STR4##的化合物反应来制备,其中X表示卤素原子或OH,烷基--SO.sub.3或芳基--SO.sub.3基团或两个X符号在一起表示一个二价氧原子,从而完成一个吗啡啶环。
