Participants

Reaction Steps

To a suspension of 500 mg of 3-bromo-1,2,4-thiadiazolo [4,5-a]benzimidazole in 50 mL methanol was added 790 μL of phenethyl mercaptan. The solid rapidly dissolves. After completion of the reaction, the solvent was evaporated and the residue purified by chromatography to give 296 mg of 2-mercapto-1-benzimidazolecarbonitrile: 1H NMR (DMSO-d6) δ12.85 (br s, 1H, SH), 7.5-7.2 (m, 4H, 4×ArH) ppm; IR (KBr) ν 2259, 1509, 1459, 1303, 1189, 752 cm-1 ; MS m/z 175 (M+), 150 (M+ -CN)
