Participants

Reaction Steps

184 mg of Ethyl 3-[3-(3-hydroxy-1-propynyl)phenyl]-2-isopropoxypropanoate was dissolved in 4 ml of dimethoxyethane, and 50 μl of phosphorous tribromide was added. After stirring was continued at room temperature overnight, the reaction mixture was diluted with ethyl acetate and washed with water and 1N hydrochloric acid. The organic layer was dried over anhydrous magnesium sulfate, filtered and the solvent was distilled off. Then, the residue was purified by silica gel column chromatography, to give 209 mg of the title compound in the 20:1 hexane-ethyl acetate fraction.
