Versuchsvorschrift

A 10 mL reaction vessel was charged with compound 245 (100 mg, 369 μmol), compound 300 (109 mg, 387 μmol), tris(dibenzylideneacetone)dipalladium (0) (25.3 mg, 27.6 μmol), 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (32.0 mg, 55.3 μmol), sodium t-butoxide (70.8 mg, 737 μmol), and dioxane (2.5 mL). The reaction was purged with argon and heated with microwave energy (300 W) for 2.5 hours at 120° C. The reaction was added to aqueous K2CO3 (10%, 30 mL) and extracted with dichloromethane+10% methanol (3×30 mL). The combined organics were dried (MgSO4) and evaporated to give an orange oil. Preparative reverse phase HPLC (gradient elution 0.1% TFA in water/10-70% acetonitrile) afforded. a yellow oil. This residue was taken up in aqueous K2CO3 (30 mL) and extracted with dichloromethane+10% methanol (3×30 mL). The combined organics were dried (MgSO4) and evaporated to give a yellow solid. This was taken up in methanol (2 mL) and 1M HCl in ethanol (0.5 mL) was added. Diethyl ether (10 mL) was added to precipitate the product, which was filtered and dried in vacuo to give compound 299 as a yellow solid (32 mg, 17%). 1H NMR (500 MHz, DMSO-d6) δ 9.43-9.61 (m, 1 H) 9.27-9.40 (m, 1 H) 8.01-8.12 (m, 1 H) 7.91-8.01 (m, 1 H) 7.75-7.91 (m, 3 H) 7.62-7.75 (m, 1 H) 5.27-5.42 (m, 1 H) 4.14-4.28 (m, 3 H) 3.10-3.18 (m, 3 H) 3.06 (none, 3 H) 2.68 (d, J=4.65 Hz, 8 H) 2.06-2.18 (m, 2 H) 1.93-2.06 (m, 2 H) 1.80-1.93 (m, 3 H) 1.48-1.69 (m, 3 H) ppm.
