Participants

Reaction Steps

A solution of methyl (S)-4-[4-[2-(tert-butoxycarbonylamino)-3-cyclohexylpropyloxy]phenyl]benzoate (0.28 g) in a mixed solvent of methanol (14 ml) and tetrahydrofuran (3 ml) was treated with 1N-sodium hydroxide aqueous solution, and the mixture was refluxed for 16 hours. After cooling, water was added to the mixture, and the acidity of the mixture was adjusted to pH 1 with 1N-hydrochloric acid. The resulting precipitate was filtered, washed with water and dried under reduced pressure to give (S)-4-[4-[2-(tert-butoxycarbonylamino)-3-cyclohexylpropyloxy]phenyl]benzoic acid (222 mg) as a white solid.
