A pyrex reaction tube was charged with 4-(7-methoxy-1,5-naphthyridin-4-yloxy)benzenamine (128 mg, 0.478 mmol), 1-(azepan-1-yl)-4-chlorophthalazine (125 mg, 0.478 mmol), TFA (0.029 ml, 0.382 mmol) and 2.4 mL of 2-BuOH. The tube was sealed and the reaction mixture was heated at 100° C. for 1.5 h. Upon cooling, EtOAc was added, and the resulting precipitate was filtered and washed with EtOAc. The solid was dissolved in 90/10/1 CH2Cl2/MeOH/NH4OH and purified by silica gel chromatography with 90/10/1 CH2Cl2/MeOH/NH4OH. The material was further purified by reverse phase chromatography (Gilson, 5-95% ACN over 15 min) to provide 4-(azepan-1-yl)-N-(4-(7-methoxy-1,5-naphthyridin-4-yloxy)phenyl)phthalazin-1-amine as a tan solid. MS m/z=493 [M+H]+. Calc'd for C29H28N6O2: 492.57.
