Procedure

Ethyl 2-octylcycloprop-2-ene-1-carboxylate (1.12 g, 5 mmol) and 100 ml of 0.2 N potassium hydroxide were stirred at room temperature for one week. Ether was added and the phases were separated. The aqueous phase was acidified and extracted with methylene chloride. The organic phase was dried over magnesium sulfate and stripped to give 0.8 g of 2-octylcycloprop-2-ene-1-carboxylic acid.
