Procedure

Stir a mixture of 1-isopropylsulfonyl-2-amino-6-(2-(2,6-difluorophenyl)-5-(phenyl)-imidazol-4-yl)-benzimidazole (0.07 g, 0.142 mmol) and 1.42 mL 1 N sodium hydroxide in 1:1 water:acetonitrile at 60° C. for 1 hour. Cool the mixture to room temperature and dilute with water and ethyl acetate. Extract the aqueous phase with ethyl acetate (3 times). Wash the combined organic phases sequentially with water and saturated aqueous sodium chloride, dry over sodium sulfate, and concentrate under reduced pressure. Subject the residue to silica gel chromatography, eluting with 2:1 dichloromethane:methanol to provide the title compound in 93% yield. MS(ES+): m/z=388.0 (M+H)+
