ABSTRACT:
Novel 5-alkanesulphonamido-2-[N-(alkanesulphonamidoheterocyclicmethyl-N-methylam ino]indane compounds have been prepared, including their pharmaceutically acceptable salts and various key novel intermediates therefor. The heterocyclic moiety present in these compounds is a benzofused heterocyclic group derived from either benzofuran or quinoline, and it is attached to the adjacent methyl group of the molecule by means of the available ring carbon atom which is situated alpha to the hetero atom. These compounds are useful in therapy as anti-arrhythmic agents and therefore, are of value in the treatment of various cardiac arrhythmias. The most preferred member compound is 5-methylanesulphonamido-2-[N-(5-methanesulphonamidobenzofur-2-ylmethyl)-N- methylamino]idane. Methods for preparing these compounds from known starting materials are provided.
