In order to obtain further proof for the structure of the δ-alkylated product, in an additional experiment, the crude reaction mixture was acetylated by acetic anhydride in pyridine. Acetylation of both, hydroxy and oxime, groups took place. The corresponding diacetate was more convenient for purification by chromatography on silica gel (benzene/ethyl acetate 7 : 3) and satisfactory spectral data were obtained.
