摘要：

Condensation of α‐halocarbonyl compounds and 2‐mercaptobenzimidazole gives thiazolo‐[3,2‐a]benzimidazoles. This condensation occurred at the mercapto group of the benzimidazole followed by cyclization to form the thiazole ring. This was confirmed by the examination of the mass spectra of 2‐ and 3‐methylthiazolo[3,2‐a]benzimidazoles, 2‐ and 3‐phenylthiazolo[3,2‐a]‐benzimidazoles, and their derivatives.
