Electric Literature of 53312-82-6, 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. 53312-82-6, name is 4-Amino-2-bromobenzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A mixture of 4-amino-2-bromobenzonitrile (440 mg, 2.2 mmol), ferf-butyl 2-oxo-6azaspiro[3.4]octane-6-carboxylate (495 mg, 2.2 mmol) and decaborane (43 mg, 0.35 mmol) in MeOH (20 mL) was stirred at 50 C overnight under Ar. The reaction mixture was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (Petroleum ether/EtOAc = 3/1) to afford intermediate 39 (406 mg, 45% yield) as a white solid.
The synthetic route of 4-Amino-2-bromobenzonitrile has been constantly updated, and we look forward to future research findings.
