Participants

Reaction Steps

An aqueous 1 M sodium hydroxide solution (3.1 mL) was added to a THF (10 mL) solution of the compound (300 mg) obtained in Example 2, followed by stirring at room temperature for 3.5 hours. THF was evaporated under reduced pressure, and 1 M hydrochloric acid was excessively added. The precipitate was collected by filtration and dried under reduced pressure to obtain [({3-[3-(3,5-difluorophenyl)-2-(1,3-dihydro-2H-benzimidazol-2-ylidene)-3-oxopropanoyl]phenyl}sulfonyl)amino]acetic acid (250 mg).
