With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1796-84-5, name is 4-Ethoxy-3-nitropyridine, molecular formula is C7H8N2O3, molecular weight is 168.15, as common compound, the synthetic route is as follows.Computed Properties of C7H8N2O3
A solution consisting of 4-ethoxy-3-nitropyridine (15.0 g, 97.3 MMOL) and EtNH2 (46.5 mL, 70% aq. solution, 584 MMOL) in ETOH (30 mL) was stirred at 85 C in a pressure vessel for 2 h. Removal of all VOLATILES IN VACUO afforded the title compound (16.2 g, 99 %). MS (ES+) m/z 168 (M+H) +.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1796-84-5, 4-Ethoxy-3-nitropyridine, and friends who are interested can also refer to it.
