Procedure

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 (100 mg), 5-(4-bromo-3,5-dimethylphenyl)pyrimidine (85 mg), K3PO4 (90 mg) are suspended in toluene (1 mL) and water (100 μL) and purged for 10 minutes with argon. Palladium-(II)-acetate (2.4 mg) and dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (S-Phos) (8.8 mg) are added, the vial is sealed and the mixture is stirred at 100° C. for 12 hours. The mixture is diluted with tetrahydrofuran and purified by HPLC on reversed phase to give the title compound. Yield: 40 mg; Mass spectrum (ESI+): m/z=525 [M+H]+.
