that position 2 is flexible for substituents with various nitrogen heterocyclics while position 3 is very sensitive to change; the most potent compounds contained a 5-nitrothiophen-2-yl ring at position 3 and either benzimidazol-2-yl (11) or a 5-benzyl-1H-[1,2,4]-triazol-3-yl (7) group at position 2 of acrylonitrile. SARs for the thiophen-2-yl-benzimidazoles show the following trend for position 5: NO2
