実験手順

104.0 mg of 4-{2-[1-Benzhydryl-5-chloro-2-(3-hydroxy-propyl)-1H-indol-3-yl]-ethoxy}-benzoic acid methyl ester (0.0002M, 1.0 eq.) was dissolved in 2.0 mL of anhydrous methylene chloride. To the solution 116.0 mg of polystyrene bound triphenylphosphine was added (1.61 mmol/g, 0.0002M, 1.0 eq.) followed by 125.0 mg of carbon tetrabromide (0.0004M, 2 eq.). The suspension was stirred for 2 hrs at room temperature at which point the reaction was filtered and the filtrate evaporated to an orange oil. The oil was purified via column chromatography with ethyl acetate/hexanes (2:98) to give 100 mg (86%) of 4-{2-[1-Benzhydryl-2-(3-bromo-propyl)-5-chloro-1H-indol-3-yl]-ethoxy}-benzoic acid methyl ester title as a yellow foam.
