Electric Literature of 583-39-1, The chemical industry reduces the impact on the environment during synthesis 583-39-1, name is 2-Mercaptobenzimidazole, I believe this compound will play a more active role in future production and life.
Thione 2b (150 mg, 1.0 mmol) was added to a stirred solution of MeOK (77 mg, 1.1 mmol) in anhydrous MeOH (2 ml). The obtained solution was added to ketone 1d (311 mg, 1.0 mmol) in anhydrous MeOH (5 ml). The reaction mixture was stirred for 24 h, the precipitate that formed was filtered off, washed with cold 70% EtOH, and air-dried. Yield 245 mg (53%), light yellow crystals, mp 153-154C (Me2CO-H2O).
