The (E,E)-1-bromo-2,4-pentadecadien-6,9-diyne (13.8 g) was dissolved in tetrahydrothiophene (14 mL) and then treated with an aqueous methanol solution (30 mL, 9:1). The two phase system was stirred at room temperature for 40 min (clear, one phase after 5-10 min) and then concentrated, 40° at 20 mmHg and room temperature at 0.5 mm for 10 min, to give the (E,E)-2,4-pentadecadien-6,9-diyn-1-yl tetrahydrothiophenium bromide as a semi-solid (24.2 g).
