Reaction Steps

p-Methoxyphenethyltriphenylphosphonium bromide (3.40 g, 7.12 mmol, 1.0 equiv.) in THF (14 mL), was cooled to 0° C. After adding n-BuLi (1.6 M in hexanes, 4.5 mL, 7.12 mmol, 1.0 equiv.) at 0° C., the red solution was stirred at 65° C. for 1 h. The mixture was re-cooled to 0° C., 2-methylundecanal (1.97 g, 10.7 mmol, 1.5 equiv.) in THF (6 mL) was added, and the mixture was stirred at 70° C. for 14 h. After addition of H2O, the aqueous layer was extracted with cyclohexane (2×), the combined organic phases were washed with brine, dried (MgSO4), filtered and the filtrate was concentrated. The residue was purified by flash chromatography on SiO2 (cyclohexane/EtOAc 98:2) to yield 1.36 g (63%) of the title compound as a light yellow oil.
