反応手順
2-Chlorobenzimidazole (0.033 moles, 5.0 g), 4-nitrothiophenol (0.033 moles, 4.14 g), and DBU (0.033 moles, 5.0 g) in 200 ml ethanol were heated at 55° C. for 3 hr. The reaction was concentrated, ethyl acetate added, washed with water, dried over sodium sulfate and the solvent removed. The solid was slurred in hexane to yield 2-(4-nitrophenylthio)benzimidazole 1.37 g, 15%. Mass Spec (FD) 271. Calculated for C13H8N3O2S: C, 57.55; H, 3.34; N, 15.49. Found: C, 57.50; H, 5.54; N, 15.23.
