Abstract

The well-known methods of synthesis of 2, 3dihydrobenzimidazole derivatives are the reactions of aldehydes or ketones with o-phenylenediamine. The products of the reactions are often a mixture of compounds that are difficult to separate (7-3). Recent publicatkns describe the synthesis of derhratives of 2-thloxo-2, 3dihydrobenzimMazole in the reaction of o-phenylene dllsocyanate with amines (4), and of derivatives of 2-oxo-2, ...
