Related Products of 6091-64-1, 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. 6091-64-1, name is Ethyl 2-bromobenzoate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: A mixture of copper powder (63.5 mg, 1.00 mmol), the aryl halide (500 mumol), 2-aminoethanol (74.9 muL, 1.25 mmol), and TMSN3 (133 muL, 1.00 mmol) in DMA (1 mL) in a 15 mL test tube was stirred under an Ar atmosphere (balloon) at 95 C using a Chemistation personal organic synthesizer (EYELA, Tokyo). After complete consumption of the aryl halide was confirmed by TLC analyses or after 24 h (if the reaction was incomplete within 24 h), the mixture was diluted with EtOAc (10 mL) and then filtered through a Celite pad. The pad was successively washed with EtOAc (20 mL), H2O (25 mL), and concd aq ammonia solution (5 mL). After the two layers were separated, the aqueous layer was extracted with EtOAc (2×10 mL). The combined organic layers were washed with brine (20 mL), dried over MgSO4, filtered, and concentrated under reduced pressure. The residue was purified by silica-gel column chromatography with n-hexane/EtOAc or n-pentane/Et2O as the eluent.
The synthetic route of Ethyl 2-bromobenzoate has been constantly updated, and we look forward to future research findings.
