A solution of (6Z,15Z)-henicosa-6,15-dien-11-yl methanesulfonate 5 (7.6 g, 19.6 mmol) and sodium cyanide (4.8 g, 98.1 mmol) in anhydrous DMF (60 mL) was heated to 60° C. overnight. Upon completion, the reaction mixture was poured into water (200 mL) and extracted with ethyl acetate (3×100 mL). The combine ethyl acetate extracts were washed with brine (3×100 mL), dried on magnesium sulfate, filtered and concentrated in vacuo to dryness. The product was purified by column chromatography (100% Hexanes to 1% ethyl acetate in hexanes) to afford (Z)-2-((Z)-dec-4-enyl)dodec-6-enenitrile 6 as a colorless oil (6.6 g, 97%). Rf 0.75 (10% EtOAc-Hexanes).
