Acetic Acid → 1-[2-(2,6-Diethyl-4-methylphenyl)-2-oxoacetyl]-2-(1-methylsulfanyl-2-propylidene)hydrazine

Participants

Reaction Steps

To a 200 ml volume four-necked flask, 2-(2,6-diethyl-4-methylphenyl)-2-oxoacetohydrazine ((12-1)-(11)-39) (6.44 g), tetrahydrofuran (72 ml), and acetic acid (1.65 g) were added under a nitrogen atmosphere. 1-methylsulfanyl-2-propanone (7-0-1) (3.12 g) was added at room temperature, and the mixture was stirred at room temperature for 2 hours. To the reaction mixture was added water (30 ml), and extracted with tert-butyl methyl ether. The organic layer was concentrated under reduced pressure to give 7.17 g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-2-(1-methylsulfanyl-2-propylidene)hydrazine ((4-4)-(8)-39).
