Versuchsvorschrift

To a 100 ml volume three-necked flask, 1-[2-(2,4,6-triethylphenyl)-2-oxoacetyl]-1-methylhydrazine ((12-2)-(11)-40) (3.01 g) was added, and to the mixture was added dropwise a solution of 1,1,1-trifluoro-3-methylsulfanyl-2-propanone (7-0-2) (2.10 g) in toluene (27 g), followed by the addition of para-toluenesulfonic acid monohydrate (0.030 g). The resulting mixture was stirred under reflux for 40 minutes. Then, the reaction mixture was cooled to room temperature, poured into water (30 ml), and extracted with ethyl acetate (50 ml) 3 times. The resulting organic layer was dried over magnesium sulfate, concentrated under reduced pressure, and subjected to silica gel column chromatography (chloroform) to give 2.31 g of 1-[2-(2,4,6-triethylphenyl)-2-oxoacetyl]-2-(1,1,1-trifluoro-3-methylsulfanyl-2-propylidene)-1-methylhydrazine ((4-46)-(1)-40).
