실험 절차

Methyl 2-((S)-6-((R)-4-bromo-7-fluoro-2,3-dihydro-1H-inden-1-yloxy)-2,3-dihydrobenzofuran-3-yl)acetate [intermediate 1, step 3] (32 mg), 2-(2,6-dimethyl-4-(3-(methylsulfonyl)propoxy)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (42 mg), [1,1′-bis(diphenylphosphino)-ferrocene]-dichloropalladium-(II) (6 mg), 1,1′-bis(diphenylphosphino)-ferrocene (4 mg) and caesium carbonate (50 mg) are suspended in toluene (2 mL) and degassed for 5 minutes with a flow of nitrogen. The mixture is heated under microwave irradiation for 90 minutes at 120° C. The mixture is diluted with ethyl acetate, washed with water, the organic phase dried and the solvent removed under vacuum. The residue is purified by chromatography on silica gel (cyclohexane/ethyl acetate 100:0→50:50) to give the title compound (9 mg). LC (method 19): tR=1.38 min; Mass spectrum: m/z=583 [M+H]+.
