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. 31037-02-2, name is Ethyl 5-amino-1-methyl-1H-pyrazole-4-carboxylate, A new synthetic method of this compound is introduced below., SDS of cas: 31037-02-2<\/a><\/p>\n

Step 3.1 : 5-Amino-1 -methyl- 1 H-pyrazole-4-carboxylic acid5-Amino-1-methyl-1 H-pyrazole-4-carboxylic acid ethyl ester (16.4 g, 97 mmol) is heated to reflux in 97 ml of 2 M sodium hydroxide solution and 100 ml of ethanol. After complete saponification, the mixture is acidified to pH 5 with 6 M HCI solution, and the formed precipitate is isolated by filtration. The product is dried at the high vacuum pump and the title compound is isolated as a white solid. HPLC: tR = 4.65 min; MS-ES+: (M+H)+ = 142 ; TLC*: Rf = 0.24.<\/p>\n

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.<\/p>\n","protected":false},"excerpt":{"rendered":"
