Reaction Steps

To a vial containing a solution of 2-(2,6-dichloro-phenyl)-3H-benzoimidazol-5-ylamine in dioxane (0.2 M, 0.10 mL) was added DIPEA (0.5 M in toluene, 0.050 mL) and acetic acid (0.2 M in toluene, 0.12 mL), followed by BOP reagent (0.2 M in DMF, 0.15 mL). After overnight at ambient temperature, the mixture was then diluted by MeOH and the whole was loaded onto a solid phase extraction (SPE) cartridge that contained strong cation exchange (SCX) (1 g media in 6 mL cartridge, United Chemical Technology). Wash-to-waste (5 mL MeOH) was followed by elute-to-collect (5 mL 20:2:1 ethyl acetate-MeOH-Et3N) and, after evaporation of volatiles, the crude was further purified by silica gel column chromatography to N-[2-(2-Chloro-phenyl)-3H-benzoimidazol-5-yl]-acetamide: MS (m/z) 320.02 (M+1).
