Versuchsvorschrift
A resealable reaction tube was charged with cesium carbonate (0.873 g, 0.268 mmol), 3-bromo-4-chloropyridine hydrochloride (0.205 g, 0.894 mmol) and 4-(4-phenylphthalazin-1-ylamino)phenol (0.280 g, 0.894 mmol) and purged with nitrogen for several minutes. 1.8 mL of DMSO was added, the tube was sealed, and the reaction mixture was heated to 130° C. for 3 h. Upon cooling the mixture was diluted with EtOAc and washed with water. The aqueous portion was extracted with EtOAc, and the combined organic portions were dried with MgSO4 and concentrated. N-(4-(3-bromopyridin-4-yloxy)phenyl)-4-phenylphthalazin-1-amine was isolated as an orange solid. MS m/z=470 [M+H]+. Calc'd for C25H17BrN4O: 469.33.
