To (6Z,16Z)-12-((Z)-dec-4-enyl)docosa-6,16-dien-11-yl 6-bromohexanoate 10 (3.1 g, 4.9 mmol) in a teflon sealed pressure vessel was added 5.6 M dimethylamine in ethanol (20 mL) and the reaction was heated to 70° C. and stirred overnight. Once complete, the reaction was concentrated in vacuo to dryness. The residue was dissolved in ethyl acetate (100 mL) and washed with sodium bicarbonate solution (2×50 mL). The ethyl acetate layer was dried on magnesium sulfate, filtered, and concentrated in vacuo to dryness. The residue was purified by column chromatography (100% EtOAc) to afford (6Z,16Z)-12-((Z)-dec-4-enyl)docosa-6,16-dien-11-yl 6-(dimethylamino)hexanoate 11 as a pale yellow oil (2.0 g, 69%), 1H NMR (400 MHz, CDCl3) δ 5.36 (m, 6H), 4.93 (m, 1H), 2.27 (m, 10H), 2.00 (m, 12H), 1.63 (m, 6H), 1.51 (m, 6H), 1.28 (m, 25H), 0.90 (m, 9H). Rf 0.3 (10% MeOH—CH2Cl2).
