To a solution of 30 mg (0.065 mmol) O-2 in 1 mL DMF in a microwave vial was added approximately 20 uL (˜0.15 mmol) tetramethyltin and 8 mg (˜10 mol %) tetrakistriphenylphosphinepalladium(0). The reaction was heated by microwave irradiation for 20 minutes at 150° C. After cooling, the reaction was purified by reverse phase HPLC (CH3CN/H2O with TFA as modifier), and the fractions containing the product were partitioned between EtOAc and saturated aqueous NaHCO3. The organic layer was washed with brine, dried over Na2SO4, filtered and concentrated to provide R-1 as a white solid (14 mg, 49% yield). HRMS m/z (M+H) 445.1977 found, 445.1983 required.
