Electric Literature of 23628-31-1, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 23628-31-1, name is 6-Aminopicolinic acid, molecular formula is C6H6N2O2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Example 3. Preparation of 2-(4-fluoro-2-(trifluoromethyl)phenyl)-N-(6- (morpholinomethyl) pyridine-2-yl)-3H-imidazo[4,5-b]pyridine-7-carboxamide (Compound 110):; Step 1) Synthesis of ethyl 6-aminopicolinate (10): 9 10To a solution of 2-amino-6-pyridinecarboxylic acid (9; 6.0 g, 43.5 mmol) in ethanol (150 mL) was added SOCl2 (12.0 g, 101.0 mmol) at 0 0C. The resulting reaction mixture was stirred under reflux for 12 h. Upon cooling to room temperature, the reaction mixture was concentrated under reduced pressure. Enough saturated aqueous Na2CO3 solution was added to adjust the pH = 9. The mixture was concentrated under reduced pressure and dichloromethane (150 mL) was added to the resulting residue. The mixture was stirred vigorously at room temperature for 30 min and then filtered. The filtrate was concentrated under reduced pressure to afford ethyl 6-aminopicolinate 10 (5.5 g, 76%). MS (ESI) calcd for C8Hi0N2O2: 166.2; found: 167 [M+H].
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 23628-31-1, 6-Aminopicolinic acid.
