Versuchsvorschrift
A solution of ethyl 2-(Z)-hydroxyimino-3-oxopentanoate (10 g) in 10 ml of acetic acid was cooled to 0° C. and treated dropwise with sulfuryl chloride (5.3 ml). The mixture was stirred for 3 hours at room temperature and quenched by ice-water. The mixture was extracted with ethyl acetate, and the extracts were washed with brine and dried with magnesium sulfate. The solvent was removed under reduced pressure to afford ethyl 4-chloro-2-(Z)-hydroxyimino-3-oxopentanoate (11.97 g).
