The invention relates to novel piperazine derivatives having the formula (I), ##STR1## wherein R.sub.1 represents a C.sub.1-5 alkyl group having optionally a phenyl, trimethoxyphenyl, phenoxy, methoxy-cyclohexyl or heptamethyleneimino substituent on the terminal carbon atom, allyl group, a phenyl group having optionally one or more halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, trihalomethyl or allyl substituent(s), or a C.sub.2-5 alkoxycarbonyl group, R.sub.2 represents hydrogen or a C.sub.1-4 alkyl group, and R.sub.3 represents furyl group, 9-xanthenyl group or a C.sub.5-6 cycloalkyl group having a C.sub.1-4 alkoxy substituent, Or acid addition salts or quaternary salts thereof. The invention also relates to pharmaceutical compositions containing the above compounds, furthermore to a process for the preparation of the novel compounds and pharmaceutical compositions. The novel compounds according to the invention possess anti-arrhythmic and coronary dilatating effects. The novel compounds can be prepared by reacting a compound of the formula (II) ##STR2## with a compound of the formula (III), R.sup.3 --COOH (III) or a reactive derivative thereof.
