Versuchsvorschrift

Magnesium 3-benzyloxyphenylsulfinate bromide, as described above in Step B, (4.5 g, 14 mmol) was dissolved in dry CH2Cl2 (175 mL) and cooled to 0° C. under argon. Sulfuryl chloride (19 mL of a 1.0 M solution in CH2Cl2, 19 mmol) was added dropwise, and the mixture was stirred for 18 hours at ambient temperature, during which time a precipitate formed. The precipitate was removed by filtration and the filtrate was concentrated under reduced pressure to give the product as a yellow oil.
