Electric Literature of 4110-35-4, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 4110-35-4 as follows.
3,5-dinitro-benzonitrile (3 g, 16 mmol), 6-methylpyridin-3-ol (1.7 g, 16 mmol), and K2CO3 (4.3 g, 31 mmol) were dissolved in DMF and heated to 1 10 C overnight. The reaction mixture was poured into water and the mixture was extracted with EtOAc. The combined organics were washed with brine, dried (Na2S04), concentrated in vacuo and purified by silica gel chromatography to provide 3-(6- methylpyridin-3-yloxy)-5-nitrobenzonitrile (3 g, 76% yield ).
