New facile synthesis of 2-substituted aminobenzimidazoles.
In this investigation, the cyclodesulphurization of N-o-aminophenyl-N'-phenylthiourea to produce 2-phenylaminobenzimidazole under the influence of dimethylsulphate was thoroughly studied under different reaction conditions. The mechanism of such reaction was also suggested.
