Application of 1214334-70-9, 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.1214334-70-9, name is 5-Bromo-6-methoxypicolinic acid, molecular formula is C7H6BrNO3, molecular weight is 232.0314, as common compound, the synthetic route is as follows.
To a solution of 5-bromo-6-methoxy picolinicacid1 (1.5 g, 0.00646 mol) in DMF (15mL, 10 vol), cooledto 0oC Na2CO3 (685 mg, 0.00646 mol) and MeI (0.834 mL,0.0129 mol) were added and the mixture was stirred for 16hat room temperature. Water was added, extracted with ethylacetate, concentrated under reduced pressure to obtain 5-bromo-6-methoxy-pyridine-2-carboxylic acid methyl ester(1.5 g, 0.00609 mol) in EtOH (15mL), NH2NH2.H2O (1.21 g,0.0243 mol) was added and the mixture was stirred for 3h at70oC, cooled to room temperature, solvents were evaporated,water (15mL) was added, filtered the reaction mass, to givepure compound 2.
Statistics shows that 1214334-70-9 is playing an increasingly important role. we look forward to future research findings about 5-Bromo-6-methoxypicolinic acid.
