Reaction Steps

(2E,4E)-Dodeca-2,4-dien-1-ol (4.95 g) was dissolved in dry toluene (110 ml) and diphenylphosphinyl azide (7.92 g) was added. DBU (4.91 ml) was added dropwise. The mixture turned opaque under evolution of heat. The solvent was evaporated and diethyl ether was added to the residue. The reaction mixture was washed with 1M HCl, 1M NaOH and brine and the organic layer was dried over sodium sulfate, filtered and concentrated to give a light yellow liquid. The crude product was filtered over silica gel.
