Reaction Steps
A suspension of 5-iodo-2,3-dioxolanebenzoic acid methyl ester (0.1 g, 0.32 mmol), potassium carbonate (0.048 g, 0.35 mmol), tetrakis(triphenylphosphine)palladium (1 mol %) and trimethylboraxine (0.089 ml, 0.64 mmol) in 1,4-dioxane (5 ml) is stirred under nitrogen at 105° C. for 10 hours. Solvent is removed and the residue is taken in ethyl acetate (50 ml). This mixture is washed with water (30 ml), dried with sodium sulphate and evaporated. Purification by chromatography (ethyl acetate/hexane 5:95) gives 5-methyl-2,3-dioxolanebenzoic acid methyl ester; GC/MS: 194 (M+1)+.
