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.36052-27-4, name is Methyl 3-aminopicolinate, molecular formula is C7H8N2O2, molecular weight is 152.15, as common compound, the synthetic route is as follows.Product Details of 36052-27-4
Step 2;. Preparation of 3-amino-6-bromo-pyridine-2-carboxylic acid methyl ester; Add a solution of 2 M sulfuric acid (2 mL) to a suspension of 3-amino-pyridine-2- carboxylic acid methyl ester (0.59 g, 3.88 mmol) in water (10 mL) and stir the mixture until the precipitate is dissolved. Add dropwise a solution of bromine (0.199 mL, 3.88 mmol) in acetic acid (1.5 mL). Add a solution of 2 M sodium hydroxide until pH = 6 and extract with ethyl acetate. Separate the organic layer and extract with ethyl acetate. Dry the combined organic layers over anhydrous sodium sulfate, filter, and remove the solvent under reduced pressure. Purify the residue using silica gel chromatography eluting with ethyl acetate/hexanes to afford the title compound (0.616 g, 69%). H-NMR (CDCl3,300 MHz) : No. 3.90 (s, 3 H) ; 6.90 (d, J = 8.5 Hz, 1H), 7.30 (d, J= 8.5 Hz, 1H).
