Reaction Steps

A pyrex reaction tube was charged with 4-(4-(4-chlorophenyl)phthalazin-1-ylamino)phenol hydrochloride (344 mg, 894 μmol), 3-(benzyloxy)-8-chloro-1,5-naphthyridine (220 mg, 813 μmol), cesium carbonate (662 mg, 2032 μmol) and 4.1 mL DMSO. The tube was sealed and the mixture was heated at 100° C. for 4 h. Water was added and the resulting precipitate was filtered, washed with water and dried. The crude material was purified by silica gel chromatography, 90/10/1 DCM/MeOH/NH4OH in DCM to provide N-(4-(7-(benzyloxy)-1,5-naphthyridin-4-yloxy)phenyl)-4-(4-chlorophenyl)phthalazin-1-amine. MS: [M+H]=583.
