Adding a certain compound to certain chemical reactions, such as: 51940-64-8, Ethyl 2,4-Dichloro-5-pyrimidinecarboxylate, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Application In Synthesis of Ethyl 2,4-Dichloro-5-pyrimidinecarboxylate, blongs to pyrimidines compound. Application In Synthesis of Ethyl 2,4-Dichloro-5-pyrimidinecarboxylate
Diisoprolylethylamine (1.38 mL, 7.72 mmol) and aniline (0.35 mL, 3.86 mmol) were added sequentially to a stirred solution of ii (0.850 g, 3.86 mmol) in acetonitrile (15 mL). The mixture was stirred at room temperature for 1 h, poured onto water (20 mL) and extracted with EtOAc (3 x 30 mL). The combined organic fraction was dried (MgSC ) and reduced in vacuo to give the crude product as a beige crystalline solid. Column chromatography (S1O2), eluting with 9: 1 Hexanes-EtOAc afforded compound iii (1.00 g, 3.61 mmol, 94%) as a colourless crystalline solid. *H NMR (300MHz, CDC13): delta 10.45 (1H, br s, 4- NH), 8.83 (1H, s), 7.66 (2H, d, 78.2), 7.40 (2H, t, J 7.7), 7.20 (1H, t, 77.7), 4.43 (2H, q, J 7.2), 1.44 (3H, t, J 7.2); [M+H]+ rn/z = 278.0.
The synthetic route of 51940-64-8 has been constantly updated, and we look forward to future research findings.
