Procedure

A solution of the mesylate 61 (1.09 g, 2.01 mmol) in toluene (30 mL) was successively treated with N,N-dimethylaminobutanol (1.34 mL, 10.1 mmol) and NaH (442 mg as a 60% dispersion in oil, 11.1 mmol). Once gas evolution ceased the reaction mixture was brought to reflux (115° C. bath temp.) and stirred (50 h). The reaction mixture was then cooled (rt) and poured into cold water and then extracted with EtOAc. The combined organics were washed with water and brine, dried (Na2SO4), filtered, concentrated and purified via chromatography (100% EtOAc) to yield 4-(((6Z,16Z)-12-((Z)-dec-4-en-1-yl)docosa-6,16-dien-11-yl)oxy)-N,N-dimethylbutan-1-amine 62 (143 mg, 13%) as a pale yellow oil. 1H NMR (400 MHz, CDCl3) δ 5.41-5.30 (m, 6H), 3.46-3.35 (m, 2H), 3.19-3.14 (m, 1H), 2.34 (t, 2H), 2.24 (s, 6H), 2.10-1.93 (m, 12H), 1.60-1.09 (m, 35H), 0.90 (t, 9H). Rf 0.54 (10% MeOH—CH2Cl2).
