実験手順
A solution of (E,E)-4-ethyl-2,4-hexadien-1-ol (2.0 g) and ethyl isocyanate (1.13 g) in 1,2-dichloroethane (12 ml) was stirred at 0° C. for 3 hours and at room temperature for 12 hours. The reaction mixture was washed with water and brine, dried over anhydrous magnesium sulfate, and evaporated in vacuo. The residue was chromatographed on silica gel (chloroform) to give (E,E)-4-ethyl-2,4-hexadien-1-yl ethylcarbamate (2.5 g) as an oil.
