반응 단계

To a 100 mL volume three-necked flask, 10.0 g of 2-(2,6-diethyl-4-methylphenyl)-2-oxoacetohydrazide ((12-1)-(11)-39), 38 ml of methanol and 4.79 ml of acetaldehyde were added and the mixture was stirred at room temperature for 1 hour. The reaction mixture was concentrated under reduced pressure, and the residue was washed with hexane and dried under reduced pressure to give 9.71 g of 2-ethylidene-1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]hydrazine ((40-a)-(14)-2) as a mixture (5:1) of geometrical isomer.
