実験手順

To a solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-(2-bromo-5-nitrobenzyl)-4-methyl-1,3-oxazolidin-2-one (3.877 g, 7.35 mmol) in a toluene (24 mL): ethanol (12 mL): water (6 mL) mixture was added (4-fluoro-5-isopropyl-2-methoxyphenyl)boronic acid (2.337 g, 11.03 mmol), tetrakis (triphenylphosphine) palladium(0) (425 mg, 5 mol %) and sodium carbonate (1.56 g, 14.72 mmol). The resulting mixture was bubbled with nitrogen and then heated in a 90° C. oil bath for 10 h. An aliquot showed complete consumption of the starting material. The reaction was quenched with brine. The resulting mixture was extracted with EtOAc and dried over Na2SO4. The resulting glassy mixture was purified by SiO2 (Biotage 40S cartridge, EtOAc/hexane, gradient). The titled compound was obtained as a crystalline solid. LC-MS: 615.26 (M+1)+. 1H NMR (CDCl3, 500 MHz) δ 1:1 mixture of rotamers δ 8.31 (s, 1 H), 8.20-8.26 (m, 1 H), 7.86 (s, 1 H), 7.70 (s, 2 H), 7.39-7.43 (m, 1 H), 6.96-7.01 (m, 1H), 6.67-6.72 (m, 1H), 5.64 (d, J=8.0 Hz, 0.5H), 5.48 (d, J=8.0 Hz, 0.5H), 4.90 (d, J=16.3 Hz, 0.5H), 4.86 (d, J=16.3 Hz, 0.5 H), 4.10-4.16 (m, 0.5 H), 3.84-3.94 (m, 1.5 H), 3.77 (s, 1.5H), 3.75 (s, 1.5H), 3.15-3.26 (m, 1H), 1.15-1.29 (m, 6 H), 0.57 (d, J=6.6 Hz, 1.5 H), 0.40 (d, J=6.6 Hz, 1.5 H).
