実験手順

Under a nitrogen atmosphere, one drop of pyridine was added to 2.5 g of phytanic acid and 12.5 ml of methylene chloride, and 1.43 g of thionyl chloride was added dropwise thereto at room temperature. After the completion of dropwise addition, the resultant was refluxed for 1 hour, and concentrated under reduced pressure to obtain about 2.6 g of phytanic acid chloride.
