Procedure

466 g of 4,4-dimethyl-2-pentynoic acid was blended with 3.5 liters of methylene chloride and stirred. 483 g of thionyl chloride was added thereto and reacted for 1 hour and then heated under reflux, whereby a hydrogen chloride gas was vigorously generated. After the reaction system was heated under reflux for 2 hours, the solvent was distilled away under reduced pressure. The product was a colorless liquid having a boiling point of about 70° C. at 20 mm Hg. Yield: 290 g, 54.3%.
