Reaction Steps

85 mg of 6-[[1-phenyl-2-propylmercapto-1H-benzimidazol-6-yl]oxy]hexanoic acid methyl ester was dissolved in 2 ml of dichloromethane, mixed with 59 mg of m-chloroperbenzoic acid (about 60%), and the mixture was stirred for 9 hours at 20° C. It was mixed with sodium disulfite solution, extracted twice with dichloromethane, the combined organic phases were washed with saturated sodium bicarbonate solution, water and saturated sodium chloride solution, dried on sodium sulfate and concentrated by evaporation in a vacuum. The residue was purified by column chromatography on silica gel. 30 mg was obtained.
