실험 절차

To a 100 ml volume three-necked flask, 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methylhydrazine ((12-2)-(11)-39) (3.04 g) was placed at room temperature, and added dropwise a solution of 1,1,1-trifluoro-3-methylsulfanyl-2-propanone (7-0-2) (2.29 g) in toluene (27 g). After para-toluenesulfonic acid monohydrate (0.028 g) was added, the resulting mixture was stirred under reflux for 45 minutes, and cooled to room temperature. The reaction mixture was poured into water (30 ml), and extracted with ethyl acetate (50 ml) 2 times. The resulting organic layer was dried over magnesium sulfate, concentrated under reduced pressure, and subjected to silica gel column chromatography (chloroform) to give 2.13 g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-2-(1,1,1-trifluoro-3-methylsulfanyl-2-propylidene)-1-methylhydrazine ((4-46)-(1)-39).
