Reaction Steps

To a solution of dilinoleyl methanol (1.0 g, 1.9 mmol) and pyridine (230 μL, 4.7 mmol) in anhydrous ether (10 mL) cooled to −15° C. under nitrogen was slowly added diphosgene (0.38 mL, 3.14 mmol). The reaction was stirred for 1 hour at −15° C., then N,N-dimethyl-N′-ethyl-ethylenediamine (2.2 mL, 14.2 mmol) was added. The solution was warmed to room temperature and stirred for 30 minutes. The solution was diluted with diethyl ether (50 mL) and filtered to remove the urea and ammonium salts. The ether filtrate was concentrated in vacuo to dryness and the residue was purified by column chromatography (100% ethyl acetate) to afford the title compound as a colorless oil (990 mg, 78%). 1H NMR (400 MHz, CDCl3): δ 5.41-5.27 (m, 8H), 4.77-4.69 (m, 1H), 3.55-3.20 (m, 4H), 2.79-2.72 (m, 4H), 2.72-2.56 (m, 1H), 2.55-2.21 (m, 7H), 2.08-1.96 (m, 8H), 1.58-1.44 (m, 4H), 1.39-1.15 (m, 36H), 1.10 (t, J=7.0 Hz, 3H), 0.90-0.82 (m, 6H).
