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 651734-54-2 as follows. Safety of 2,6-Difluoro-3,5-dimethoxyaniline
To a stirred slurry of 2,6-difluoro-3,5-dimethoxyaniline (500 mg, 2.64 mmol) in 6.0 M hydrogen chloride in water (4 mL, 24 mmol) was added a solution of sodium nitrite (191 mg, 2.78 mmol) in water (1 mL) dropwise over 15 min at 0 C. After stirring the resulting mixture at 0 C. for another 15 min, a solution of potassium iodide (1.8 g, 10. mmol) in water (2 mL) was slowly added to the resulting orange-red slurry at 0 C. with vigorus stirring. After completion of the addition, the reaction mixture was allowed to warm up to r.t. for 1 hour. The solid was collected by filtration, washed with water and dried under vacuum. 570 mg solid was collected and used directly in the next step.
According to the analysis of related databases, 651734-54-2, the application of this compound in the production field has become more and more popular.
