Reaction Steps

A solution of hydrogen chloride (5 mL; 13 equiv; 20 mmoles) (4 M in dioxane) and (R)-2-methyl-propane-2-sulfinic acid [(S)-1-(3-bromo-phenyl)-3-hydroxy-1-methyl-butyl]-amide (570 mg, 1.6 mmoles, 1.0 equiv) as a single diastereomer is stirred for 5 minutes. The solvent is removed under reduced pressure and the residue is made basic with saturated aqueous sodium bicarbonate. The aqueous phase is extracted with dichloromethane. The organic phase is dried over sodium sulfate, filtered, and concentrated under reduced pressure to give the title compound: MS (m/z): 358, 360 (M+1).
