Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 59290-82-3, name is 3-Nitroisonicotinic acid. A new synthetic method of this compound is introduced below., Recommanded Product: 3-Nitroisonicotinic acid

Example 87; N-MethvI-3-(2-(2-oxoindolin-5-vIamino)-5-ftrifluoromethyl)pyridin-4-ylamino)isonicotinamide; JV-Methyl-3-nitroisonicotinamide; To the mixture of 3-nitroisonicotinic acid (4.78 g, 28.4 mmol), methylamine hydrogen chloride (2.88 g, 1.5 eq), EDC (6.53 g, 1.2 eq), HOBt (4.59 g, 1.2 eq) in DMF (5OmL) was added DIEA (25 mL, 5.0 eq). The mixture was stirred at room temperature overnight. It was concentrated and the crude was dissolved in EtOAc. It was washed with saturated NaHCO3 solution. The solvent was removed and the crude was purified by silica gel chromatography (0%~20% MeOH/DCM) to obtain the desired product 7V-methyl-3-nitroisonicotinamide (878 mg, isolated yield 17%).
