A substituted anilide derivative of the formula ##STR1## wherein R.sub.1 represents a mononuclear or binuclear heterocyclic group which contains 1 to 3 nitrogen atoms as ring members and may have a substituent. A represents a single bond, a carbonyl group, a sulfur atom, or a lower alkylene group which may be substituted by a hydroxyl group, R.sub.2 represents a hydrogen atom, a halogen atom, a lower alkyl group, a trifluoromethyl group, a lower alkenyloxy group, or a C.sub.1 -C.sub.14 alkoxy group which may have a substituent, R.sub.3 and R.sub.4 are identical or different, and each represents a hydrogen atom, a lower alkyl group, a phenyl group, or a phenyl(lower alkyl) group which may have a substitutent, or taken together, may form a saturated nitrogen-containing heterocyclic group together with the nitrogen atom to which they are bonded, and B represents a single bond or a lower alkylene group which may have a substituent, or an acid addition salt thereof. The compound of formula (I) or a pharmaceutically acceptable acid addition salt thereof is useful for the manufacture of antiarrhythmically active medicaments.
一种替代苯胺衍生物的化学式##STR1##其中R.sub.1代表一个含有1至3个氮原子作为环成员的单核或双核杂环基团,可能带有取代基。A代表一个单键,一个羰基,一个硫原子,或一个可能被羟基取代的较低烷基烯基团,R.sub.2代表一个氢原子,一个卤素原子,一个较低烷基基团,一个三氟甲基基团,一个较低烯氧基团,或一个可能带有取代基的C.sub.1-C.sub.14烷氧基团,R.sub.3和R.sub.4相同或不同,每个代表一个氢原子,一个较低烷基基团,一个苯基,或一个苯基(较低烷基)基团,可能带有取代基,或者一起形成一个饱和氮含杂环基团,与它们连接的氮原子一起,B代表一个单键或一个可能带有取代基的较低烷基烯基团,或其酸盐。化合物的化学式(I)或其药学上可接受的酸盐用于制造具有抗心律失常活性的药物。
