107 mg (0.39 mmol) (RS)—S-(4-nitrophenyl)-N-(2-methoxy-acetyl)-S-methylsulfoximide is dissolved in 13.6 ml ethanol and treated with 40 mg palladium on activated charcoal (10% Pd). The mixture is stirred under hydrogen at normal pressure for 60 minutes at 24 C. The catalyst is filtered off and the solution concentrated. After chromatographic purification (silica gel, hexane/ethyl acetate (0-50% ethyl acetate)), 50 mg (53%) of the desired product is obtained.
