Related Products of 866775-18-0, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.866775-18-0, name is Methyl 3-amino-6-bromo-5-(trifluoromethyl)picolinate, molecular formula is C8H6BrF3N2O2, molecular weight is 299.05, as common compound, the synthetic route is as follows.
3-Amino-6-bromo-5-trifluoromethyl-pyridine-2-carboxylic acid methyl ester (1.40 g, 4.68 mmol) was suspended in MeOH (15 mL); Sodium hydroxide (2.0 M aqueous solution) (14.04 mL, 28.1 mmol) was added and the suspension was stirred at RT overnight. The reaction mixture was concentrated in vacuo and the resulting residue was dissolved in water (100 mL) and then acidifed by the addition of 5.0M HCI(aq). The product was extracted into ethyl acetate (2 x 75 mL) and the combined organic extracts were washed with water (50 mL), brine (25 mL), dried (MgS04) and concentrated in vacuo to afford the title product as a yellow solid. H-NMR: [400MHz, DMSO-d6] ? 13.24 (1 H, br s, C02H), 7.74 (1 H, s, ArH), 7.17 92H, br s ArNH2). m/z 285.1 , 287.1 [M+H]+
