As a common heterocyclic compound, it belong naphthyridine compound,2-Methyl[1,8]-Naphthyridine,1569-16-0,Molecular formula: C9H8N2,mainly used in chemical industry, its synthesis route is as follows.,1569-16-0
adding 0.3 mmol of 2-methyl-1,8-naphthyridine, 0.75 mmol of elemental iodine, and 2 mL of dimethyl sulfoxide to a 15 mL pressure-resistant tube.The reaction was stirred magnetically at 110 C for 4 hours. After the reaction was cooled, 0.36 mmol of p-toluenesulfonylhydrazide and 0.9 mmol of potassium phosphate trihydrate were added, and magnetic stirring was carried out at 110 C for 6 hours. After the reaction was completed, the reaction solution was completed. Extraction, organic layer washing, drying, distillation under reduced pressure to obtain a crude product, crude product with petroleum ether / ethyl acetate = 1.5:1 ~ 2:1 (V / V) as the eluent for column separation and purification The desired product, the product is a yellow solid with a yield of 65%.
With the synthetic route has been constantly updated, we look forward to future research findings about 2-Methyl[1,8]-Naphthyridine,belong naphthyridine compound
