실험 절차

To a solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-(2-bromo-5-nitrobenzyl)-4-methyl-1,3-oxazolidin-2-one (950 mg, 1.80 mmol) in a toluene (5.2 mL): ethanol (2.6 mL): water (1.3 mL) mixture was added (2-chloro-5-isopropylphenyl) boronic acid (325 mg, 1.64 mmol), tetrakis(triphenylphosphine)palladium(0) (188 mg, 10 mol %) and sodium carbonate (346 mg, 3.26 mmol). The resulting mixture was heated in an 80° C. oil bath for 12 h. The reaction crude was evaporated into dryness. The resulting residue was taken up by a mixture of water and EtOAc. The combined organic extracts were dried over Na2SO4 and concentrated in vacuo to give the crude product, which was purified by SiO2 (Biotage 40+S cartridge, EtOAc/hexane, gradient) to afford the titled compound. LC-MS: 601.19 (M+1)+. 1H NMR (CDCl3, 500 MHz) a 1:1 mixture of rotamers δ 8.31-8.30 (m, 1H), 8.24-8.28 (m, 1H), 7.85-7.89 (m, 1H), 7.68-7.76 (m, 2H), 7.42-7.48 (m, 2H), 7.26-7.30 (m, 1H), 7.04-7.11 (m, 1H), 5.74 (d, J=7.8 Hz, 0.5H), 5.58 (d, J=8.0 Hz, 0.5H), 4.92 (d, J=15.8 Hz, 0.5H), 4.76 (d, J=16.2 Hz, 0.5H), 3.97-4.04 (m, 1.5H), 3.82 (dt, J=8.0, 6.6 Hz, 0.5H), 2.89-2.99 (m, 1H) 1.22-1.29 (m, 6H), 0.60 (d, J=6.4 Hz, 1.5H), 0.52 (d, J=6.6 Hz, 1.5H).
