Versuchsvorschrift

To a mixture of 4,4,5,5-tetramethyl-2-[4-(toluene-2-sulfonyl)-phenyl]-[1,3,2]dioxaborolane (50 mg, 0.14 mmol), (6-fluoro-3-methyl-4-trifluoromethanesulfonyloxy-naphthalen-2-yl)-acetic acid methyl ester (73 mg, 0.19 mmol), K3PO4 (81 mg, 0.38 mmol), palladium(II) acetate (14 mg, 0.06 mmol), and 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (49 mg, 0.12 mmol) were added anhydrous toluene (4 mL) and water (400 uL) at room temperature. The resulting light brown solution was heated to 125° C. for 15 hours. The reaction mixture was cooled to room temperature and diluted with brine solution and ethyl acetate. The two layers were separated and the aqueous layer was extracted with ethyl acetate and the combined extracts were washed with brine solution. The organic layer was dried over anhydrous MgSO4. Filtration and concentration gave a crude residue which was purified using an ISCO (40 g) column, eluting with 0-40% ethyl acetate in hexanes, to give {6-fluoro-3-methyl-4-[4-(toluene-2-sulfonyl)-phenyl]-naphthalen-2-yl}-acetic acid methyl ester (20 mg, 31%). 1H NMR (300 MHz, CDCl3) δ ppm 8.31 (d, J=7.5 Hz, 1 H), 8.01 (d, J=7.8 Hz, 2 H), 7.80 (dd, J=8.5, 6.0 Hz, 1 H), 7.75 (s, 1 H), 7.50-7.62 (m, 1 H), 7.47 (d, J=7.5 Hz, 1 H), 7.40 (d, J=7.8 Hz, 2 H), 7.32 (d, J=7.2 Hz, 1 H), 7.19 (td, J=8.5, 2.0 Hz, 1 H), 6.72 (d, J=10.9 Hz, 1 H), 3.85 (s, 2 H), 3.73 (s, 3 H), 2.56 (s, 3 H), 2.09 (s, 3 H). HRMS calcd. for C27H24FO4S [(M+H)+] 463.1374, obsd. 463.1373.
