It is a common heterocyclic compound, the naphthyridine compound, 8-Chloro-2-methoxy-1,5-naphthyridine, cas is 249889-68-7 its synthesis route is as follows.

Example 13; iV-(l-ethyl-lJ-pyrazol-4-yl)-2-[2-methoxy-4-(6-methoxy-l,5-naphthyridin- 4~yloxy)phenyl] acetamide; A mixture of 4-chloro-6-methoxy-l,5-naphthyridine (0.08 g), JV-(I -ethyl-lH-pyrazol-4- yl)-2-(4-hydroxy-2-methoxyphenyl)acetamide (0.113 g), 4-dimethylaminopyridine (0.151 g) and chlorobenzene (1 ml) was stirred and heated under argon to 140C for 14 hours. The resultant mixture was cooled to ambient temperature and partitioned between methylene chloride and 2N aqueous hydrochloric acid. The organic extract was dried over magnesium sulphate and evaporated. The residue was purified by column chromatography on silica using a solvent gradient from ethyl acetate to a 19:1 mixture of ethyl acetate and methanol as eluent. There was thus obtained the title compound as a solid (0.018 g); 1H NMR Spectrum:5 (DMSOd6) 1.32 (t, 3H), 3.58 (s, 2H), 3.75 (s, 3H), 3.95 (s, 3H), 4.07 (q, 2H), 6.79 (m, IH), 6.91 (d, IH), 6.93 (d, IH), 7.29 (d, IH), 7.31 (d, IH), 7.41 (s, IH), 7.87 (s, IH), 8.28 (d, IH), 8.61 (d, IH), 10.01 (s, IH); Mass Spectrum: M+H+ 434.
