Application of 24241-18-7, 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. 24241-18-7, name is 2-Amino-3,5-dibromopyrazine belongs to Pyrazines compound, it is a common compound, a new synthetic route is introduced below.
Example 54; Step 1; A suspension of 1 (3 g, 11.64 mmol) in 25% aq. NH4OH (15 mL) in sealed tube was heated at 110 C. for 16 h. After completion of reaction (reaction progress was monitored by TLC), the reaction mixture was partitioned between ethyl acetate-water (3¡Á50 mL). The combined extracts were washed with saturated brine, dried and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel eluted with 15% ethyl acetate-hexane to afford 2 as a yellow solid (2.1 g, 93%). MS m/z (ES): 189 (M+H)+.
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-3,5-dibromopyrazine, other downstream synthetic routes, hurry up and to see.
