실험 절차

In a microwave vial, methyl 2-((S)-6-((R)-7-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-inden-1-yloxy)-2,3-dihydrobenzofuran-3-yl)acetate (75 mg), 4-iodo-N,3,5-trimethylbenzamide (93 mg), K3PO4 (102 mg) and dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (S-Phos) (7 mg) are suspended in toluene (1.8 mL) and water (0.2 mL) and purged for 10 minutes with argon. Palladium-(II)-acetate (4 mg) is added, the vial is sealed and the mixture is stirred at 120° C. for 5 hours. After cooling to ambient temperature the mixture is partitioned between ethyl acetate and water. The organic phase is dried (MgSO4) and concentrated. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 100:0→80:20) to give the title compound. Yield: 16 mg; LC (method 25): tR=1.32 min; Mass spectrum (ESI+): m/z=504 [M+H]+.
