4928-88-5, 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. 4928-88-5 name is Methyl 1H-1,2,4-triazole-3-carboxylate, This 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 12 A mixture of methyl 1,2,4-triazole-3-carboxylate (1.27 g, 0.01 mole) and beta-D-ribofuranosyl-1,2,3,5-tetraacetate (3.18 g, 0.01 mole) was melted and then 0.048 g of methanesulfonic acid was added thereto. The reaction mixture was reacted for hours, while maintaining the temperature of the reaction mixture at 95+-5¡ã C. And then, the reaction mixture was crystallized with 300.8 nit of methanol to give 3.0 g of 1-(2,3,5-tri-O-acetyl-beta-D-ribofuranosyl)-1,2,4-triazole-3-carboxylic acid methyl ester (yield: 79percent).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Methyl 1H-1,2,4-triazole-3-carboxylate, and friends who are interested can also refer to it.
