As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 89694-10-0, name is 2-Methoxy-3-methyl-5-nitropyridine, molecular formula is C7H8N2O3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Application In Synthesis of 2-Methoxy-3-methyl-5-nitropyridine
(lc) 6-Methoxy-5-methyl-3-pyridinamine [Formula 10]; 2-Methoxy-3-methyl-5-nitropyridine (1.63 g, 9.71 mmol) was dissolved in methanol (50 ml), 10% Pd- on-carbon powder (50% water content article) (800 mg) was added, and stirred under hydrogen atmosphere for 2 hours and 10 minutes. After the reaction was completed, celite filtration was carried out, the solvent was evaporated, thereby yielding the title compound (1.25 g, 0.90 mmol, 93%) as a blue oily substance. ¹H NMR(400 MHz, DMSO-d6) 8 ppm; 2.03(3H, s), 3.73(3H, s), 4.62 (2H, s), 6.83-6.86(lH, m), 7.31-7.34(lH, m),
With the rapid development of chemical substances, we look forward to future research findings about 89694-10-0.
