Reaction Conditions

Reaction Steps

Fifty grams (50 g) of 2,2-dimethyl-3-(1-butenyl)cyclopropanecarboxylic acid, 350 ml of hexane and 0.6 g of N,N-dimethylformamide were mixed together. At 50° C., 39 g of thionyl chloride was eye-dropped thereto over 30 minutes. Subsequently, the reaction mixture was stirred for 1 hour at 50° C. The reaction mixture was then concentrated under reduced pressure to provide 48 g of 2,2-dimethyl-3-(1-butenyl)cyclopropane carboxylic chloride.
