A solution of 5 g of para-n-pentyl-transcyclohexanoic acid is refluxed in 8 ml of thionyl chloride for 2 hours. The thionyl chloride is then eliminated by distilling under atmospheric pressure. The acid chloride is then distilled under reduced pressure and under a dry nitrogen stream. This gives a product with a boiling point of 87° C. under 0.5 mm Hg.
