Versuchsvorschrift
2-[1-(3-Chloroallyloxyimino)butyl]-3-hydroxy-5-(4,6-dimethoxy-2-methylthio-5-pyrimidyl)cyclohex-2-en-1-one (6) was prepared from 2-butyryl-3-hydroxy-5-[5-(4,6-dimethoxy-2-methylthiopyrimidyl]cyclohex-2-en-1-one (see Example 3) and 3-chloroallyloxyamine hydrochloride following essentially the same procedure as that described in Example 1, part (iv). The product was obtained as a nearly colourless oil and was characterized by nuclear resonance spectroscopy.
