Adding a certain compound to certain chemical reactions, such as: 1214337-05-9, Methyl 6-chloro-5-fluoropicolinate, 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, category: pyridine-derivatives, blongs to pyridine-derivatives compound. category: pyridine-derivatives
Step 3: Synthesis of 6-chloro-5-fluoropicolinic acid [514] Methyl 6-chloro-5-fluoropicolinate (1.35 g, 7.095 mmol) was dissolved in THF:H20 = 6:1 (42 ml), followed by addition of lithium hydroxide monohydrate (596 mg, 14.19 mmol), and then the resulting mixture was stirred at room temperature for 3 hours. The resulting reaction liquid was concentrated under reduced pressure, dissolved by addition of distilled water (20 ml), acidified by slow addition of 1N aqueous HCl solution, and then extracted with 5% MeOH/MC (30 ml x 2). The organic layer was dried over anhydrous sodium sulfate, followed by filtration, concentration, and vacuum drying, to obtain 1.04 g of white solid (80%). [515]
The synthetic route of 1214337-05-9 has been constantly updated, and we look forward to future research findings.
