Reaction Steps

4-Bromo-indanone (500 mg, 2.37 mmol), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (137 mg, 0.24 mmol), thioacetate (541 mg, 4.74 mmol) and diisopropylethylamine (1.64 mL, 5.69 mmol) are dissolved in 1,4-dioxane (2 mL). The mixture is degassed with N2 and tris(dibenzylideneacetone)palladium(0) (217 mg, 0.24 mmol) is added and heated under microwave irradiation at 120° C. for 2 hours. The solution is concentrated under vacuum. The crude product obtained is purified by flash chromatography (10-80% ethyl acetate in cyclohexane) to give the title compound (Yield: 210 mg). LC (METHOD 5): tR=0.89 min; Mass spectrum (ES−): m/z=163 [M−H]−.
