Reaction Steps

A stirred solution of 4-(1H-benzimidazol-1-ylmethyl)benzonitrile (0.50 g, 2.14 mmol) and triethylamine (Et3N) (0.24 g, 2.37 mmol) in pyridine (2 mL), was bubbled through with H2S (g) at room temperature for 2 h. The reaction mixture was diluted with water and filtered. The filtercake was washed with cold water and dried under vacuum to afford the title compound in 87% yield, identified by NMR and mass spectral analyses. 1H NMR (400 MHz, DMSO-d6): 5.54 (s, 2H), 7.16-7.22 (m, 2H), 7.30 (d, J=8.8 Hz, 2H), 7.45-7.52 (m, 1H), 7.62-7.68 (m, 1H), 7.79 (d, J=8.8 Hz, 2H), 9.30 (bs, 1H), 9.80 (bs, 1H). LCMS (ESI+) 268 (MH+).
