With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.54920-82-0,1,7-Naphthyridin-2(1H)-one,as a common compound, the synthetic route is as follows.,54920-82-0
To a solution of lH-l,7-naphthyridin-2-one (1.6 g, 11.0 mmol) in MeOH (50 mL) was added BnBr (2.1 g, 12.1 mmol) at to 70 ¡ãC. The resulting mixture was stirred at 70 ¡ãC for 3 hrs and then cooled to 0 ¡ãC. To the cooled mixture was added NaBH4 (2.09 g, 55.0 mmol). The resulting mixture was slowly warmed to rt and stirred for 3 hrs at rt. The reaction was quenched with 6N HC1 (20 mL). The resulting mixture was stirred at rt for 2 hrs, then basified with 2 N NaOH to pH 10 and extracted with DCM (50 mL) twice. The combined organic layer was dried over Na2S04 and concentrated in vacuo. The residue was purified by column (eluting with DCM: MeOH =40:1, v:v) to give 7-benzyl-l,5,6,8-tetrahydro-l,7-naphthyridin-2-one (700 mg) as a yellow solid.
54920-82-0 1,7-Naphthyridin-2(1H)-one 589676, anaphthyridine compound, is more and more widely used in various fields.
