Versuchsvorschrift

A 10 mL reaction vessel was charged with compound 245 (80.0 mg, 295 μmol), 1-(6-chloropyridin-3-yl)-3,5-dimethylpiperazine (66.6 mg, 295 μmol), tris(dibenzylideneacetone)dipalladium (0) (20.3 mg, 22.1 μmol), 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (25.6 mg, 44.2 μmol), sodium t-butoxide (56.7 mg, 590 μmol), and dioxane (2.5 mL). The reaction was purged with argon and heated with microwave energy (300 W) for 3.5 hours at 120° C. The reaction was taken up in ethyl acetate (40 mL) and washed with water (30 mL) and brine (30 mL). The organic phase was dried (MgSO4) and evaporated to give an orange oil. Silica gel chromatography (gradient elution hexanes+2.5% TEA/0-100% ethyl acetate+2.5% TEA, then ethyl acetate+2.5% TEA, 0-8% methanol) afforded a yellow solid. This residue was taken up in 2 mL methanol (2 mL) and 1M ethanolic HCl (1 mL) was added, followed by the addition of diethyl ether (20 mL). The resulting precipitate was collected and dried in vacuo to give compound 289 as a yellow solid (91 mg, 67%) 1H NMR (500 MHz, DMSO-d6) δ 9.54-9.67 (m, 2 H) 9.47-9.54 (m, 1 H) 9.05-9.23 (m, 1 H) 8.19-8.30 (m, 1 H) 8.06-8.17 (m, 3 H) 7.94-8.04 (m, 1 H) 7.81-7.94 (m, 1 H) 5.45-5.58 (m, 1 H) 3.81-3.94 (m, 2 H) 3.34-3.48 (m, 2 H) 2.75-2.91 (m, 2 H) 2.23-2.35 (m, 2 H) 2.10-2.20 (m, 2 H) 2.05 (none, 2 H) 1.68-1.86 (m, 2 H) 1.34 (d, J=6.60 Hz, 7 H) ppm.
