Adding a certain compound to certain chemical reactions, such as: 868551-30-8, Methyl 4-methyl-5-nitropicolinate, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, HPLC of Formula: C8H8N2O4, blongs to pyridine-derivatives compound. HPLC of Formula: C8H8N2O4
To a solution of methyl 4-methyl-5-nitropicolinate (810 mg, 4.1 mmol) in ethanol (150 ml) was added palladium on carbon (10 wt.%, 85 mg, 4.1 mmol) at room temperature. Hydrogenation was carried out in a parr shaker at 45 psi for 3 h. Additional palladium on carbon was added (170 mg) and the reaction was continued at 39 psi for 23 h. The mixture was filtered through CELITE and concentrated to provide methyl 5-amino-4-methylpicolinate, which was directly used in the next step without further purification. LC-MS (IE, m/z): 167 [M + 1]+
At the same time, in my other blogs, there are other synthetic methods of this type of compound,868551-30-8, Methyl 4-methyl-5-nitropicolinate, and friends who are interested can also refer to it.
