Synthetic Route of 866775-18-0, Adding some certain compound to certain chemical reactions, such as: 866775-18-0, name is Methyl 3-amino-6-bromo-5-(trifluoromethyl)picolinate,molecular formula is C8H6BrF3N2O2, 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 866775-18-0.

A suspension of 3-amino-6-bromo-5-trifluoromethyl-pyridine-2-carboxylic acid methyl ester (Intermediate A4) (1.00 g, 3.34 mmol) in dry MeOH (20 ml) was stirred at reflux (85 C) for 30 min and then treated with hydrazine monohydrate (324 ul, 6.69 mmol). The mixture was returned to heat at reflux for 5h 30 min and allowed to cool to RT. Water was added and the resulting precipitate was collected by filtration and dried in a vacuum oven to afford the title compound as a biege solid; 1 H NMR (400 MHz, DMSO-d6) ? 9.50 (1 H, s), 7.69 (1 H, s), 7.19 (2H, s), 4.55 (2H). LCMS: Rt =1.15 min; [M+H]+ 299 Method 2minl_C_v002.

According to the analysis of related databases, 866775-18-0, the application of this compound in the production field has become more and more popular.
