497-25-6, Oxazolidin-2-one is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,497-25-6
A 48 mL pressure vessel containing 2-bromo-4-fluorobenzonitrile (1.00 g, 5.00 mmol), 2-oxazolidone (0.390 g, 4.50 mmol), K2CO3 (0.970 g, 7.0 mmol) and xantphos (0.231 g, 0.40 mmol) in dioxane (10 mL) was degassed with argon for 15 min. Pd2 dba3 (0.140 g, 0.15 mmol) was introduced and then the reaction mixture was heated at 70 C. for 18 h. The mixture was cooled, diluted with dioxane, and then filtered through Celite. The resulting mixture was concentrated in vacuo and subjected to column chromatography on silica gel with hexanes:ethyl acetate (1:1) to (3:7) gradient as the eluent to afford the title compound as a white solid (0.460 g, 50% yield): 1H NMR (400 MHz, CDCl3) ? ppm: 7.73 (1H, dd, J=5.8, 8.6 Hz), 7.43 (1H, dd, J=2.5, 9.6 Hz), 7.11 (1H, ddd, J=2.5, 7.5, 8.7 Hz), 4.60 (2H, t, J=7.1 Hz), 4.29 (2H, t, J=7.1 HJz); LCMS (+ESI, M+H+) m/z 207.
As the paragraph descriping shows that 497-25-6 is playing an increasingly important role.
