The benzylgroup is a protectinggroup for benzimidazoles and imidazoles that can survive acidic, basic, oxidizing, and reducing conditions. Deprotection, however, can require vigorous and potentially non-chemoselective methods. The triethylsilane–Pd/C reduction system is an exceptionally mild, convenient, and efficientmethod for deprotecting N-benzylbenzimidazoles that are unsubstituted at the 2-
