Versuchsvorschrift

A solution of 2-chloro-5-methyl-4-nitrobenzaldehyde (1.72 g, 8.6 mmol) in acetic acid (20 ml) at 80° C. was treated with sodium perborate (2.64 g, 17.2 mmol). After 0.5 h a further portion of sodium perborate (1.32 g, 8.6 mmol) was added. After 0.25 h the reaction mixture was added to ethyl acetate--half saturated brine, and the organic extract dried (Na2SO4) and evaporated, affording the title product as a white solid (1.43 g, 77%).
