Reference of 110223-15-9, 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. 110223-15-9, name is 2-Amino-3-benzyloxypyrazine belongs to pyrazines compound, it is a common compound, a new synthetic route is introduced below.
General procedure: For aromatic urea derivatives; the appropriate aromatic isocyanate(3.0 mmol) was added to a solution of the appropriate 2-amino-3-benzyloxy pyrazine derivative (2.5 mmol) in THF(10 mL). The reaction was refluxed for 3e6 h. After cooling, thereaction mixture was evaporated and the residue was purified byprecipitation in cold methanol and filtered to give the targetcompound(s). For aliphatic urea derivatives; the appropriatealiphatic isocyanate derivative (1.02 mmol) was added to a solutionof the appropriate 2-amino-3-benzyloxy pyrazine derivative(0.85 mmol) in dry THF (5 mL) in the presence of NaH (60% inmineral oil, 68 mg, 1.71 mmol). The reaction was refluxed for 5 h.After cooling, the reaction mixture was evaporated and the residuewas purified by flash column chromatography (SiO2, EA/n-Hex 1/4).
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, 2-Amino-3-benzyloxypyrazine, other downstream synthetic routes, hurry up and to see.
