HCID 178506090HCID 178506090, compound

Procedure

A mixture of 4-(trifluoromethyl)-1,2-phenylenediamine (3.0 g), formic acid (1.3 mL), and hydrochloric acid (4 M, 17 mL) was heated to reflux for 45 minutes. The mixture was allowed to cool to room temperature and neutralized with concentrated ammonium hydroxide. The aqueous layer was decanted off to give 5-trifluoromethyl-1H-benzimidazole (2.56 g) as a black solid. ESI-MS (m/z) 187 [M+H]+.
