Reaction Steps

To a suspension of 50 g 4-oxo-undecanoic acid (Synthesis, 1987, 408) in 350 ml of ether, 22.15 g pyridine was added in at 0° C. Then a solution of 32.72 g thionyl chloride in 50 ml of ether was added in at 0-5° C. and then the reaction mixture was stirred for 20 hours at room temperature. Then the reaction mixture was filtered and evaporated to dryness. The residue (53.83 g yellow oil) was not further purified.
