ABSTRACT:
Calcium antagonists of the formula ##STR1## with R(1), R(2), R(3) and R(4) being, inter alia, H, alkyl, alkoxy, halogen, in some cases phenyl; m being 1-4; n being 0-3; X being CH.sub.2, O, S, CO, CHOH or CR.sub.2, and R(5) being various groups containing nitrogen atoms, are described.
They are obtained by reaction of compounds II which are likewise new and which contain in place of R(5) a leaving group Y (Cl, Br, I) with the appropriate (cyclic) amino compound.
Another synthesis comprises reaction of the appropriate indollinone derivative IV which has a non-etherified hydroxyl group with a side chain which contains a terminal leaving group Z (Cl, Br, I) in the presence of a base.
Furthermore, indolinone derivatives VI with an ether side chain with a terminal epoxide group can be reacted with (cyclic) amines to give compounds I.
