Adding a certain compound to certain chemical reactions, such as: 632365-54-9, name is Methyl 5-amino-1H-pyrazole-3-carboxylate, belongs to pyrazoles-derivatives compound, 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 632365-54-9, COA of Formula: C5H7N3O2
Step C. Methyl 3-amino-lH-pyrazole 5-carboxylate (325 mg, 2.3 mmol) and methyl acetoacetate (330mg, 2.3 mmol) in methanol (10 mL) were heated to reflux for 2h and cooled down. The resulting precipitate was collected to give white solid product 7-Methyl-pyrazolo[l,5-a]pyrimidine-2,5-dicarboxylic acid dimethyl ester (356 mg, yield 62%). MS (M + H): 250.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 5-amino-1H-pyrazole-3-carboxylate, other downstream synthetic routes, hurry up and to see.
