Methyl 3-isoquinolinecarboxylate

Cream powder

Add to 250ml eggplant(3S) -1, 2, 3, 4-tetrahydroisoquinoline-3-carboxylate (2) (4.23 g, 22.15 mmol)The solution was dissolved by adding N, N-dimethylformamide (50 ml)Potassium permanganate (2.97 g, 18.79 mmol)The reaction was added after 6 hEthanol (50 ml) was stirred for 30 min, Remove the solvent, add methanol (30ml) re-dissolved.The residue was purified by column chromatography to give a colorless solid (858 mg, 24.56percent).The compound 3-isoquinolinecarboxylic acid (0801-132) (1.0 g, 5.78 mmol, 1.0 eq.)Dissolved in 30 ml of methanol, Sulfuric acid (0.5 ml) was then added and the reaction was refluxed overnight.After the reaction is finished, add sodium bicarbonate solutionpH to 8, extracted with dichloromethane, liquid-separated, and the organic phase dried over anhydrous sodium sulfate.Spin-drying afforded the compound 3-isoquinolinecarboxylic acid methyl ester (810 mg, 75percent).
