실험 절차

To a 25 ml volume three-necked flask, 1-methyl-2-(1-methylsulfonyl-2-propylidene)hydrazine (5-2-1) (670 mg), tetrahydrofuran (anhydrous) (2.25 ml), and triethylamine (390 mg) were added under a nitrogen atmosphere. To the mixture, 2-[5-(4-chlorophenyl)-2-ethylphenyl]-2-oxoacetyl chloride (6-c) (937 mg) was added dropwise at 0° C. and stirred for 2 hours. To hexane (15 ml) in a 50 ml volume three-necked flask, the reaction mixture was added dropwise, stirred for 10 minutes, and filtered. The residue was dried under reduced pressure, dissolved in ethyl acetate, and filtered again. The filtrate was concentrated under reduced pressure to give 853 mg of 1-[2-[5-(4-chlorophenyl)-2-ethylphenyl]-2-oxoacetyl]-1-methyl-2-(1-methylsulfonyl-2-propylidene)hydrazine ((4-34)-(1)-67). The filtrate from the first filtration was concentrated under reduced pressure, the residue was subjected to column chromatography (hexane:ethyl acetate=1.5:1) to give 240 mg of additional 1-[2-[5-(4-chlorophenyl)-2-ethylphenyl]-2-oxoacetyl]-1-methyl-2-(1-methylsulfonyl-2-propylidene)hydrazine ((4-34)-(1)-67).
