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.22280-60-0, name is 6-Chloro-2-methyl-3-nitropyridine, molecular formula is C6H5ClN2O2, molecular weight is 172.57, as common compound, the synthetic route is as follows.Recommanded Product: 22280-60-0
Sodium metal (0.119g, 5.1mmol) was dissolved in methanol (6ml) at 0C (ice bath), 6-chloro-2-methyl-3-nitro-pyridine (0.30g, 1.7mmol) was added and the mixture was stirred at 0C until the complete consumption of 6-chloro-2-methyl-3-nitro-pyridine (4h). Acetic acid (0.306g, 5.1mmol) was added and the solution was concentrated under reduced pressure. The residue was dissolved in ethyl acetate (20 ml), washed with water (10 ml), dried over anhydrous Na2SO4, filtered and the solvent was removed under reduced pressure to give 0.28g (97%) 6-methoxy-2-methyl-3-nitropyridine as colourless powder.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,22280-60-0, 6-Chloro-2-methyl-3-nitropyridine, and friends who are interested can also refer to it.
