Procedure

50 mg of 3-[2-[(1,2-diphenyl-1H-benzimidazol-6-yl)oxy]ethoxy]propanoic acid-tert-butyl ester was dissolved in 0.5 ml of trifluoroacetic acid and stirred for 15 hours. Then, it was diluted with water and extracted three times with ethyl acetate. The combined organic phases were washed with saturated sodium chloride solution, dried on sodium sulfate and concentrated by evaporation in a vacuum. The residue was chromatographed on silica gel.
