Abstract
2-Cyanomethylbenzothiazole reacts with 3-(5-X-2-furyl)-, 3-(2-thienyl)- or 3-(2-pyrrolyl)-2-cyanoacrylonitrile in tetrahydrofuran under catalysis of triethylamine to give 1-(2-benzothiazolyl)-1-cyano-2-heteroarylethylenes as a result of replacement of malonodinitrile by 2-cyanomethylbenzothiazole.
