실험 절차

A mixture of 262 g. (1.109 mole) of 5-(3-methyl-2-octyl)resorcinol, 283 g. (1.23 mole) of diethyl α-acetylglutarate, and 170 g. (1.11 mole) of phorphorus oxychloride protected from atmospheric mositure is stirred at room temperature for 12 days. The mixture is taken up in benzene-ether and the solution is washed several times with water, aqueous sodium bicarbonate, water and dried over anhydrous magnesium sulfate. After removal of the solvent, 441 g. of an oil is obtained, which solidifies on standing.
