10.2 parts by weight of 2-butyryl-5-(3-methyl-4-ethyl-6-isobutoxytetrahydropyran-2-yl)-cyclohexane-1,3-dione were dissolved in 100 parts by volume of ethanol, and 2.42 parts by weight of sodium acetate and 3.86 parts by weight of O-(3-chloroallyl)-hydroxylamine hydrochloride were added. The mixture was stirred for several hours at room temperature and then poured into ice-water, and the resulting mixture was extracted with methylene chloride. The methylene chloride phase was evaporated off, leaving 11.1 parts by weight of 2-(3-chloroallyloxyaminobutylidene)-5-(3-methyl-4-ethyl-6-isobutoxytetrahydropyran-2-yl)-cyclohexane-1,3-dione as a yellow oil of refractive index nD22 1.5129.
