Procedure

To a solution of (R)-methyl 3-((S)-1,1-dimethylethylsulfinamido)-3-phenylbutanoate (280 mg, 0.94 mmol) in MeOH (2 mL) and H2O (0.5 mL) was added LiOH (138 mg, 3.29 mmol). The solution was stirred for 4 h and then concentrated to give the residue. The residue was dissolved in 15% MeOH/H2O and filtered to give (R)-3-((S)-1,1-dimethylethylsulfinamido)-3-phenylbutanoic acid (266 mg, 100%). 1H NMR (CDCl3): 1.10 (s, 9H), 1.51 (s, 3H), 2.43-2.52 (d, 1H), 2.73-2.86 (d, 1H), 7.15-7.18 (m, 1H), 7.06-7.12 (m, 3H), 7.30-7.40 (m, 2H).
