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 7170-01-6 as follows. HPLC of Formula: C3H5N3
A mixture of 3 -methyl- IH-1, 2;4-triazole (6.83 g, 82 mmol), 2- chloro-5-mtrobenzomtrile (15 g, 82 mmol), and potassium carbonate (34.1 g, 246 mmol) in anhydrous acetonitrile (200 mL) was heated at 70 0C for 16 h. The dark brown reaction mixture was allowed to cool to rt and was poured into water (500 mL). The aqueous mixture was extracted with EtOAc (3 x 200 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude residue was purified using silica gel chromatography (40-100% ethyl acetate/hexane, linear gradient) to afford 2-(3-methyl~lH-l,2,4-triazol-l-yl)-5- nitrobenzonitrile (10.9 g, 58 % yield). LC-MS (M+H)+ – 230.1. 1H NMR (500 MHz, chloroform-D) delta ppm 2.53 (s, 3 H) 8.10 (d, J-9.16 Hz, 1 H) 8.56 (dd, J-9.16, 2.44 Hz, 1 H) 8.68 (d, J-2.44 Hz, 1 H) 8.93 (s, 1 H).
According to the analysis of related databases, 7170-01-6, the application of this compound in the production field has become more and more popular.
