144649-99-0, name is 5-Bromo-2-methoxybenzonitrile, belongs to nitriles-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: 144649-99-0
Example 35 1,1-Dimethylethyl {[5-bromo-2-(methyloxy)phenyl]methyl}carbamate NaBH4 (2.9 g, 75.5 mmol) was cautiously added in several portions to a solution of NiCl2 (2.6 g, 19.8 mmol), Boc2O (8.2 g, 37.7 mmol) and 5-bromo-2-(methyloxy)benzonitrile (4.0 g, 18.9 mmol) in dry EtOH (70 mL) at 0 C. Once the reaction had subsided, the mixture was left to stir at room temperature for 3 h. Ethanol was removed under reduced pressure and the residue was dissolved in EtOAc and saturated solution of NaHCO3, then filtered and the aqueous layer was repeatedly washed with EtOAc. The combined organic phases were dried Na2SO4. The crude product was purified by flash column chromatography to give the captioned the product (1.5 g yield: 25%). 1H NMR (400 MHz, CDCl3) delta 7.36-7.33 (m, 2H), 6.74 (d, J=8.8 Hz, 1H), 4.97 (br, 1H), 4.27 (d, J=4.8 Hz, 1H), 3.82 (s, 3H), 1.45 (s, 9H); 13C NMR (400 MHz, CDCl3) delta 156.5, 155.8, 131.7, 131.1, 129.3, 111.8, 79.5, 55.5, 39.9, 26.4. HPLC: retention time.
The synthetic route of 144649-99-0 has been constantly updated, and we look forward to future research findings.
