1-(Methylsulphonyl)acetone → 1-[2-(2,6-Diethyl-4-methylphenyl)-2-oxoacetyl]-1-methyl-2-(1-methylsulfonyl-2-propylidene)hydrazine

Participants

Reaction Steps

To a 20 ml volume two-necked flask, 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methylhydrazine ((12-2)-(11)-39) (0.50 g), tetrahydrofuran (anhydrous) (9 ml), and 1-methylsulfonyl-2-propanone (7-2-1) (0.30 g) were added under a nitrogen atmosphere and stirred at room temperature for 22 hours. The reaction mixture was concentrated under reduced pressure. The residue was subjected to column chromatography (hexane:acetone=3:1) to give 0.25 g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methyl-2-(1-methylsulfonyl-2-propylidene)hydrazine ((4-34-(1)-39).
