Procedure
To a solution of dilinoleylmethanol (II, 560 mg, 1 mmol) and dry triethylamine (0.44 g, 4.2 mmol) in 50 mL of anhydrous CH2Cl2 was added dropwise 3-bromopropionyl chloride (technical grade, 0.34 mL) under nitrogen. The resulting mixture was stirred at room temperature for 3 days. The organic phase was diluted with 50 mL of dichloromethane and washed with water (3×50 mL), brine (50 mL), and dried over anhydrous Na2SO4. The solvent was evaporated to afford 610 mg of brownish oil as a crude product. The crude product was purified by column chromatography on silica gel (230-400 mesh, 100 mL) with 0-3% ethyl acetate gradient in hexanes as eluent. This resulted in 540 g of a mixture of III as a major product and a by-product. The mixture was used in the following step without further purification.
