Reaction Steps
(5Z,8Z,11Z,14Z,17Z)-Icosa-5,8,11,14,17-pentaene-1-thiol (305 mg, 1.00 mmol) was added to a solution of NaH (60% in mineral oil, 44 mg, 1.10 mmol) in dry DMF (10 mL) held at 0° C. under inert atmosphere. After ten minutes ethyl bromopropionate (136 μL, 1.05 mmol) was added and the mixture was stirred for 1.5 hour at 0° C. The reaction mixture was added sat. aq. NH4Cl (20 mL) and heptane (50 mL). The phases were separated and the water phase extracted with heptane (2×25 mL). The combined organics were washed with brine (25 mL), dried (MgSO4), filtered and evaporated to give 376 mg of title compound as crude oil. Purification by flash chromatography on silica gel using gradient elution (starting pure heptane and increasing stepwise to heptane:EtOAc 95:5) afforded 318 mg (79% yield) of the title compound as oil.
