Analyzing the synthesis route of 249889-68-7

With the synthetic route has been constantly updated, we look forward to future research findings about 8-Chloro-2-methoxy-1,5-naphthyridine,belong naphthyridine compound

As a common heterocyclic compound, it belong naphthyridine compound,8-Chloro-2-methoxy-1,5-naphthyridine,249889-68-7,Molecular formula: C9H7ClN2O,mainly used in chemical industry, its synthesis route is as follows.,249889-68-7

Under an atmosphere of argon, a mixture of 4-chloro-6-methoxy-l,5-naphthyridine (0.485 g), methyl 2-(5-hydroxy-3-methoxypyridin-2-yl)acetate (0.493 g), caesium carbonate (1.63 g) and DMF (10 ml) was stirred and heated to 13O0C for 7 hours. The resultant mixture was cooled to ambient temperature and partitioned between ethyl acetate and water. The organic phase was dried over magnesium sulphate and evaporated. The residue was purified by column chromatography on silica using increasingly polar mixtures of ethyl acetate and methanol as eluent. There was thus obtained methyl 2-[3-methoxy-5-(6-methoxy- l,5-naphthyridin-4-yloxy)pyridin-2-yl]acetate as a solid (0.51 g); 1H NMR Spectrum: T/GB2007/001221- 171 -(DMSOd6) 3.63 (s, 3H), 3.79 (s, 2H), 3.8 (s, 3H)5 3.83 (s, 3H), 7.13 (d, IH), 7.29 (d, IH)5 7.44 (d, IH)5 7.98 (d, IH)5 8.3 (d, IH)5 8.68 (d, IH); Mass Spectrum: M+H+ 356.

With the synthetic route has been constantly updated, we look forward to future research findings about 8-Chloro-2-methoxy-1,5-naphthyridine,belong naphthyridine compound
