Reaction Steps
A solution of 35.5 g succinic acid mono-(3,7-dimethyl-oct-6-enyl) ester and 12.3 g pyridine in 200 ml of ether was cooled in an ice bath. Then a solution of 18.0 g thionyl chloride in 100 ml of ether was added dropwise at 5-10° C. during 90 min. The resulting solution was stirred overnight at room temperature, then it was filtered and evaporated to dryness. The residue was not further purified to yield 31.5 g of a yellow liquid.
