Versuchsvorschrift

A mixture of (4-chlorophenyl)(2,4-dichloro-3-phenylquinolin-6-yl)(pyridin-3-yl)methanol (75 mg, 0.15 mmol, Example 17), 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (37 mg, 0.18 mmol), PdCl2(dppf) (11 mg, 0.015 mmol) and K2CO3 (42 mg, 0.30 mmol) in 10 mL of dioxane was combined with 2 mL of water and heated to 70° C. After 3 hours, the reaction mixture was cooled to room temperature, diluted with EtOAc, and washed with water. The organic phase was dried over Na2SO4, filtered and concentrated. The residue was purified on an ISCO using 0-10% methanol in ethyl acetate and lyophilized to give the title compound as a white solid. 1H NMR (400 MHz, CDCl3) δ=8.60 (s, 1H), 8.55 (d, J=4.0 Hz, 1H), 8.45 (d, J=3.5 Hz, 1H), 8.27-8.34 (m, 2H), 8.15 (d, J=8.6 Hz, 1H), 7.73 (dd, J=8.6, 2.0 Hz, 2H), 7.58 (d, J=7.6 Hz, 1H), 7.28-7.36 (m, 8H), 7.08-7.16 (m, 3H); MS m/e 534.8 [M+H]+.
