Electric Literature of 3524-32-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3524-32-1, name is 5-Amino-1,3-dimethylpyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: In a 50 mL single-mouth flask,Salicylaldehyde (1 mmol) was added in sequence,Ethyl cyanoacetate (1 mmol) and 3-methyl-1-phenyl-5-aminopyrazole (1 mmol),Triethylamine (0.1 mmol) and ethanol (8 mL),The reaction was stirred under reflux for 8 h.After the reaction is over,Cool to room temperature.Rotate the solvent under reduced pressure,Get a rough product,The crude product was recrystallized from 95% ethanol.5-amino-1-methyl-3-phenylcoumarin[4,3-d]pyrazolo[3,4-b]pyridine-6(3H)-one (Ia):Yield 63%
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, 5-Amino-1,3-dimethylpyrazole, other downstream synthetic routes, hurry up and to see.
