100 mg (0.5 mmol) (RS)—S-(4-nitrophenyl)-S-methylsulfoximide (Example 1b) are dissolved in 3.33 ml dichloromethane, cooled in the ice-bath and treated with 0.1 ml (0.75 mmol) triethylamine. 0.068 ml (0.75 mmol) 2-methoxy-acetyl chloride are added dropwise with ice cooling. The mixture is stirred for 30 minutes in the ice-bath and for 15 hours at room temperature. After chromatographic purification (silica gel, hexane/ethyl acetate (0-50% ethyl acetate)), 107 mg (79%) of the desired product is obtained.
