To a 50 ml volume three-necked flask, 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methylhydrazine ((12-2)-(11)-39) (2.0 g), tetrahydrofuran (anhydrous) (5 ml), and 1-methylsulfinyl-2-propanone (7-1-1) (1.65 g) were added under a nitrogen atmosphere, and stirred at room temperature for 48 hours. The reaction mixture was concentrated under reduced pressure at room temperature. The residue was subjected to silica gel column chromatography (ethyl acetate to chloroform) to give 0.48 g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methyl-2-(1-methylsulfinyl-2-propylidene)hydrazine ((4-19)-(1)-39).
