Reaction Steps

In a nitrogen purged sealed tube, 8-chloro-3-methoxy-1,5-naphthyridine (0.053 g, 0.271 mmol) was dissolved in DMF (2.00 mL). 4-(4-(4-Tert-butylphenyl)phthalazin-1-ylamino)phenol (0.100 g, 0.271 mmol) and cesium carbonate (0.176 g, 0.541 mol) were added, and the mixture in the tube was stirred at 90° C. for 17 h. Upon cooling to RT, the mixture was concentrated in vacuo, and purified by silica gel chromatography using 0-100% CH2Cl2:MeOH(90:10)/CH2Cl2 to yield 4-(4-tert-butylphenyl)-N-(4-(7-methoxy-1,5-naphthyridin-4-yloxy)phenyl)phthalazin-1-amine as off-white solid. MS [M+H]=528.1; Calc'd 527.6 for C33H29N5O2.
