17403-47-3, 5-Nitro-2,3-dihydrobenzofuran is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of 21 (6.3 g, 38.1 mmol) and 10% palladium on carbon (1.0 g) in EtOH (50 mL) and THF (50 mL) was stirred under an atmosphere of H2 (1 atm) at room temperature for 13 h. The catalyst was removed by filtration, and then the filtrate was concentrated. The residue was purified by flash chromatography on SiO2 with a gradient eluent of 0-10% MeOH/EtOAc to provide 22 (4.63 g, 90%) as a pale brown powder; 1H NMR (CDCl3) delta: 3.12 (2H, t, J = 8.6 Hz), 3.37 (2H, s), 4.49 (2H, t, J = 8.6 Hz), 6.43-6.47 (1H, m) 6.57-6.61 (2H, m); Anal. Calcd for C8H9NO: C, 71.09; H, 6.71; N, 10.36. Found: C, 70.92; H, 6.60; N, 10.09.
17403-47-3, The synthetic route of 17403-47-3 has been constantly updated, and we look forward to future research findings.
