General procedure: (Method C5) Synthesis of N-(6-(7-methoxy-1,5-naphthyridin-4-yloxy)pyridin-3-yl)-4-phenylphthalazin-1-amine A pyrex reaction tube was charged with 8-chloro-3-methoxy-1,5-naphthyridine (50 mg, 0.26 mmol), 5-(4-phenylphthalazin-1-ylamino)pyridin-2-ol (80 mg, 0.26 mmol), cesium carbonate (249 mg, 0.76 mmol) and DMSO (2 mL). The tube was sealed and the reaction mixture was heated to 130 C. After 3.5 h, an aliquot was analyzed by LCMS, and the desired product was determined to be the major peak. The reaction mixture was diluted with DMSO and purified by Gilson HPLC {5-65% (0.1% TFA in CH3CN) in H2O over 20 min}. The product-containing fractions were combined, basified by addition of aq. NaHCO3 and extracted with DCM. The organic portion was dried with Na2SO4, filtered, and concentrated to afford material that was further purified by silica gel chromatography, 90/10/1 CH2Cl2/MeOH/NH4OH. This provided N-(6-(7-methoxy-1,5-naphthyridin-4-yloxy)pyridin-3-yl)-4-phenylphthalazin-1-amine as pure material. MS [M+H]=473.01.48 minutes. Calc’d for C28H20N6O2: 472.5.

As the paragraph descriping shows that 952059-69-7 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.952059-69-7,8-Chloro-3-methoxy-1,5-naphthyridine,as a common compound, the synthetic route is as follows.

Example 38 (Method C2); Synthesis of 4-(4-tert-butylphenyl)-N-(4-(7-methoxy-l,5-naphthyridin-4- yloxy)phenyl)phthalazin-l-amineIn a nitrogen purged sealed tube, 8-chloro-3-methoxy-l,5-naphthyridine (0.053 g, 0.271 mmol) was dissolved in DMF (2.00 mL). 4-(4-(4-Tert-butylphenyl)phthalazin-l- 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: 1O)/CH2C12 to yield 4-(4-tert-butylphenyl)-N-(4-(7-methoxy- l,5-naphthyridin-4-yloxy)phenyl)phthalazin-l -amine as off-white solid. MS [M+H]=528.1; Calc’d 527.6 for C33H29N5O2.
