Adding a certain compound to certain chemical reactions, such as: 97509-75-6, 3-Fluoropicolinonitrile, 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, Product Details of 97509-75-6, blongs to pyridine-derivatives compound. Product Details of 97509-75-6
Pre aration 86A: 3-Fluoro-4-iodopicolinonitrile[00297] To a solution of diisopropylamine (2.80 ml, 19.66 mmol) in THF (Volume: 201 ml) cooled to -78 °C was added n-butyllithium (7.86 ml, 19.66 mmol) dropwise. The dry ice/acetone bath was replaced with an ice water bath and reaction mixture was stirred at 0 °C for 25 min, and then re-cooled to -78 °C. In a separate flask, a solution of 3- fluoropicolinonitrile (1.5 g, 12.29 mmol) in THF (50 mL) was cooled to -78 °C, and then LDA (130 mL, 1.0 equiv) was added. The solution turned dark red. After 35 min, iodine (3.43 g, 13.51 mmol) was added rapidly. The reaction mixture was stirred for 45 min, then quenched with H20. Layers were separated and the aqueous phase extracted with CH2CI2 (2X). Organics combined, dried over Na2S04, filtered, and concentrated to afford a brown residue. The crude material was dissolved in a minimal amount of CH2CI2 to be chromatographed. Purification of the crude material by silica gel chromatography using an ISCO machine (80 g column, 60 mL/min, 0-20percent EtOAc in hexanes over 23 min, tr = 18 min) gave the title compound (1.7 g, 6.79 mmol, 55.2percent yield) as a brown solid.
The synthetic route of 97509-75-6 has been constantly updated, and we look forward to future research findings.
