    摘要: This invention relates to novel 2-substituted-1(4)-aryl piperazines and to a process for their preparation. The compounds of this invention have been found to have cardiovascular, primarily antiarrhythmic effects and are of the following general formula I ##STR1## wherein R is hydrogen, lower alkyl or benzyl; and R.sub.1 and R.sub.2 are the same or independently hydrogen, lower alkyl, lower alkoxy or halogen;Z is ##STR2## --NR.sub.3 --CH.sub.2 --, --OCH.sub.2 --, --NR.sub.3 --, --O-- or --NR.sub.3 SO.sub.2 -- andQ is (C.sub.1 -C.sub.4) alkyl--SO.sub.2 --NR.sub.4 -- or ##STR3## R.sub.3 is hydrogen, lower alkyl, allyl or loweralkoxyloweralkyl; and included in the descriptors of the compounds of Formula I is the proviso that when R.sub.4 is methyl then ##STR4## must be in the 2 position of Formula I.
