Reaction Steps

To a mixture of (E,E)-4-ethyl-2,4-hexadien-1-ol (2.0 g), triethylamine (8 ml), and dichloromethane (15 ml) at 0° C. was added nicotinic acid chloride hydrochloride (4.23 g). The solution was stirred at 0° C. for 1.5 hours and at room temperature for 14 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 4-ethyl-2,4-hexadien-1-yl 3-pyridinecarboxylate (3.3 g) as an oil.
