Versuchsvorschrift

Tert-butyl {2-[4-chloro-3-cyano-6-(1-hydroxyethyl)-2-vinylphenoxy]ethyl}carbamate (1.6 g, 4.4 mmol) was dissolved in methylene chloride (1.2 mL) cooled in a dry ice acetone bath and ozone/oxygen was bubbled through the solution until a persistent blue color remained. The reaction was purged with oxygen and nitrogen to remove excess ozone and dimethyl sulfide (0.80 mL, 11 mmol) was added to reduce the ozonide. After stirring for 1 h, the reaction was complete. This was concentrated in vacuo to give a residue give tert-butyl {2-[4-chloro-3-cyano-2-formyl-6-(1-hydroxyethyl)phenoxy]ethyl}carbamate. LCMS calculated for C17H21ClN2O5Na (M+Na)+: m/z=391.1; found: 391.1.
