Reaction Steps

To a solution of ethyl 2-methyl-2-(methylsulfonyl)-4-[4-(phenylthio)phenyl]butanoate (348.6 mg, 0.887 mmol) in tetrahydrofuran/methanol (4:1, 10 mL) was added a solution of lithium hydroxide monohydrate in water (1.78 M, 3.55 mmol). The mixture was stirred at ambient temperature overnight. The mixture was diluted with aqueous HCl (1N in water) and extracted with diethyl ether 2×. The combined organic extracts were washed with water, dried over magnesium sulfate, filtered and concentrated to dryness to afford 2-methyl-2-(methylsulfonyl)-4-[4-(phenylthio)phenyl]butanoic acid as a solid. 323 mg. LCMS: (M−1) 363.3.
