497-25-6,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.497-25-6,Oxazolidin-2-one,as a common compound, the synthetic route is as follows.
Example 101 (R) and (S) -3- (5′-fluoro-2,2-dimethyl-2′-oxospiro [cyclopropane- 1 ,3′-hidoline] – 1 ‘-yl) -5- (2-oxooxazolidin-3-yl)benzoic acidSynthesis of methyl-3-bromo-5-(2-oxooxazolidin-3-yl)benzoateA suspension of 3-bromo-5-iodo-benzoic acid methyl ester (682 mg, 2 mmol), oxazolidin- 2-one (191 mg, 2.2 mmol), Cul (76 mg, 0.4 mmol), potassium carbonate (545mg, 4mmol) and N, N’-dimethyl-ethane-l,2-diamine (86uL, 0.8mmol) in acetonitrile (15 mL) was stirred for 16 hours at 90C. The precipitate was filtered off and washed with ethyl acetate. The filtrate was concentrated in vacuo to afford 3-bromo-5-(2-oxo-oxazolidin-3-yl)- benzoic acid methyl ester (480 mg, 80%) which was used for next step without further purification.
The synthetic route of 497-25-6 has been constantly updated, and we look forward to future research findings.
