Versuchsvorschrift

(S)—N—((S)-(4-Formylphenyl)(3-(trifluoromethyl)pyridin-2-yl)methyl)-2-methylpropane-2-sulfinamide (0.200 g, 0.520 mmol) was dissolved in dry THF (30 mL) and cooled in an ice bath. Methylmagnesium bromide (3M in Et2O, 0.50 mL, 1.50 mmol) was added dropwise and the reaction stirred. The resulting mixture was stirred for 1 h and then quenched by addition of saturated aqueous NH4Cl (10 mL). H2O (100 mL) and EtOAc (100 mL) were added, and the phases were mixed and separated. The organic layer was dried with MgSO4 and evaporated to dryness under reduced pressure. Purification using silica chromatography (hexane to EtOAc gradient) gave impure material which was further purified using reverse phase HPLC to give the desired (S)—N-((1 S)-(4-(1-hydroxyethyl)phenyl)(3-(trifluoromethyl)pyridin-2-yl)methyl)-2-methylpropane-2-sulfinamide.
