Reaction Steps

A solution of 2', 3'-dichloro-3,3-dimethyl-spiro-[cyclopropane-1,1'-indene]-2-carboxylic acid-, ethyl ester (19 g as is, containing iodobenzene) in t-butanol (50 ml) is added to a 0.1 M solution of potassium-t-butoxide in t-butanol (450 ml; 0.045 mole) and the mixture allowed to stir overnight at room temperature. The reaction mixture is then poured into water, extracted with ether, the ether extracts dried over magnesium sulfate and evaporated to dryness to afford 11.1 g of a black oil. This oil is purified by chromatography (silica gel; eluent: 1:1 mixture of methylene chloride:hexane), to afford 2 g of title product, a yellow oil.
