Adding a certain compound to certain chemical reactions, such as: 1721-23-9, 3-Cyano-2-methylpyridine, 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, SDS of cas: 1721-23-9, blongs to pyridine-derivatives compound. SDS of cas: 1721-23-9
1-Amino-3(2-methyl-3-pyridyl)2,5-naphthyridine To 5.9 of 3-cyano-2-methylpyridine dissolved in 30 ml. of dimethylformamide, gradually add 6.7 g. of potassium t-butoxide at about 5 C. Maintain the mixture at 5 C for 4-6 hours and quench the reaction in ice water. Collect the crystalline precipitate and recrystallize from toluene to yield 1-amino-3(2-methyl-3-pyridyl)-2,5-naphthyridine.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1721-23-9, 3-Cyano-2-methylpyridine, and friends who are interested can also refer to it.
