With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.17200-30-5,6-Nitrobenzo[d]oxazole,as a common compound, the synthetic route is as follows.
General procedure: A mixture of VNU-11(Hf) (0.018 g, 0.01 mmol), aromatic acylchloride (0.140 g, 1 mmol) and benzoxazole (0.119 g, 1 mmol)was heated at 170 C under conventional heating for a few hoursor microwave irradiation of a CEM Discover apparatus for a fewminutes. After completion of reaction, the catalyst was filteredfrom the reaction mixture. The filtrate was diluted with ethyl acetate (50 mL), washed with H2O (3×20 mL), aqueous NaHCO3(2 x20 mL), and dried over Na2SO4. The solvent was removed ina rotary evaporator. The crude product was purified by flash chromatography(90:10 acetone/petroleum ether to give correspondingproduct. The purity and identity of the products were confirmed byGC-MS spectra, which were compared with the spectra in the NISTlibrary, and by 1H and 13C NMR spectroscopy.
17200-30-5, The synthetic route of 17200-30-5 has been constantly updated, and we look forward to future research findings.
