Compounds of the formula: ##STR1## or a salt thereof, wherein "Het" is a group of the formula: ##STR2## in which R.sup.1 is attached to position "a" or "b" of the benzene ring and R and R.sup.1, which are the same, are --NHSO.sub.2 (C.sub.1 -C.sub.4 alkyl), --NH.sub.2 or --NO.sub.2. The compounds in which R and R.sup.1 are --NHSO.sub.2 (C.sub.1 -C.sub.4 alkyl) are cardiac antiarrhythmic agents. The compounds in which R and R.sup.1 are --NO.sub.2 and --NH.sub.2 are synthetic intermediates.
该公式化合物为:##STR1## 或其盐,其中"Het"是一个具有以下结构的基团:##STR2## 其中R.sup.1 附着在苯环的"a"或"b"位置,而R和R.sup.1是相同的,为--NHSO.sub.2 (C.sub.1 -C.sub.4 烷基),--NH.sub.2 或--NO.sub.2。其中R和R.sup.1均为--NHSO.sub.2 (C.sub.1 -C.sub.4 烷基)的化合物为心脏抗心律失常剂。而R和R.sup.1均为--NO.sub.2 和--NH.sub.2的化合物为合成中间体。
