Reaction Steps
To a solution of (S)-2-methyl-N-((R)-1-(3-methyl-5-(trifluoromethyl)phenyl)allyl) propane-2-sulfinamide (400 mg, 1.25 mmol) in THF (10 mL) under N2 atmosphere was dropwise added LiHMDS (1.9 ml, 1 M in THF, 1.9 mmol) at −60° C. The reaction was stirred for 30 min at −60° C. followed by addition of MeI (712 mg, 32 mmol). After stirring for another 3 h at room temperature, the reaction was quenched with water at 0° C. and then extracted with EtOAc (2×100 mL). The combined organic layers were dried over anhydrous Na2SO4 and then concentrated under reduced pressure. The residue was purified by silica gel chromatography (PE/EtOAc=5/1 to 2/1) to give the title compound (300 mg, yield: 75%); m/z (ES+): 334 [M+H]+.
