Versuchsvorschrift

To a solution of (6Z,16Z)-12-((Z)-dec-4-enyl)docosa-6,16-dien-11-ol 8 (2.4 g, 5.2 mmol), 6-bromohexanoic acid (1.5 g, 7.8 mmol), EDCI hydrochloride (1.5 g, 7.8 mmol), diisopropylethylamine (2.0 g, 15.6 mmol) in anhydrous dichloromethane (25 mL) was added dimethylaminopyridine (15 mg). The solution was refluxed for 2 hours, cooled to room temperature and concentrated in vacuo to dryness. The reaction mixture was purified by column chromatography on silica gel 60 (2″ W×10″ L; eluted with 5% EtOAc/Hex) to afford (6Z,16Z)-12-((Z)-dec-4-enyl)docosa-6,16-dien-11-yl 6-bromohexanoate 10 as a colorless oil (3.1 g, 94%). Rf 0.5 (10% EtOAc-Hexanes).
