To a stirred solution of N-benzyl-N-(2-propynyl)-N-(4-octynyl)amine (377, 0.516 g,  2.0 mmol) in THF (5.0 mL) under argon at –78 °C, nBuLi (0.96 mL of 2.5 M solution in hexanes, 2.41 mmol) was added dropwise.  Pre-dried dimethyldisulphide (0.26 mL, 2.82 mmol) was added and the solution warmed to room temperature, stirred for 2 hours before quenching with a saturated solution of NaHCO3 (50.0 mL).  The product was extracted into diethyl ether (3 x 50 mL), the combined organic layer washed with water (3 x 50 mL), brine (50.0 mL), dried over MgSO4, filtered and the solvent removed under reduced pressure.  Column chromatography (SiO2, 0-100 % Et2O:petroleum including 5 % Et3N) afforded the title compound as a pungent yellow oil (540 mg, 1.80 mmol, 90 %).

*Yield (%)  90
