These common heterocyclic compound, 583-39-1, name is 2-Mercaptobenzimidazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Formula: C7H6N2S
General procedure: A mixture of 0.001 mol of chloroethynylphosphonate1a-1c and 0.002 mol of benzimidazole-2-thione 2d in 15 mL of anhydrous acetonitrile was stirred at room temperature for 2-5 h. The precipitate was filtered off. The solvent was removed from the filtrate, the precipitate was combined and recrystallizedfrom ethanol. Yields and melting points of the obtained compounds are given in Table 1.
The synthetic route of 2-Mercaptobenzimidazole has been constantly updated, and we look forward to future research findings.
