実験手順

To a solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-[(4-bromo-4′-fluoro-5′-isopropyl-2′-methoxybiphenyl-2-yl)methyl]-4-methyl-1,3-oxazolidin-2-one (100 mg, 0.15 mmol) in N,N-dimethylformamide (1.5 mL) was added copper(I) cyanide (17 mg, 0.19 mmol). The resulting reaction mixture was N2 purged and sealed in a microwave vessel. The vessel was subject to microwave irradiation at 150° C. for 30 min. LC-MS indicated only the starting bromide was present. Added tetrakis(triphenylphosphine)palladium(0) (10 mg, 6 mol %) into the reaction mixture. Repeated microwave irradiation at 150° C. for 30 min. An aliquot indicated the desired product was formed and all starting bromide was consumed. Reaction crude was partitioned between water and hexanes. The aqueous phase was back extracted with diethyl ether. The combined extracts were dried over Na2SO4. The titled compound was obtained as a glassy material after two preparative TLC plates developed respectively by 20% EtOAc in hexanes and 4% EtOAc in dichloromethane. LC-MS: 595.03 (M+1)+. 1H NMR (CDCl3, 500 MHz) a 1:1 mixture of rotamers δ 7.86 (s, 1H), 7.61 (S, 0.5H), 7.67-7.71 (m, 2.5H), 7.64-7.68 (m, 1H), 7.32-7.36 (m, 1H), 6.98 (d, J=8.5 Hz, 0.5H), 6.95 (d, J=8.5 Hz, 0.5H), 6.68 (d, J=12 Hz, 1H), 5.62 (d, J=8.0 Hz, 0.5H), 5.46 (d, J=8.0 Hz, 0.5H), 4.85 (d, J=16.0 Hz, 0.5H), 4.80 (d, J=16.0 Hz, 0.5H), 4.06 (d, J=16 Hz, 0.5H), 3.79-3.86 (m, 1H), 3.70-3.78 (m, 3.5H), 3.16-3.24 (m, 1H), 3.75 (s, 1.5H), 3.16-3.25 (m, 1H), 3.14 (s, 1.5H), 3.13 (s, 1.5H), 1.15-1.27 (m, 6H), 0.54 (d, J=7.0 Hz, 1.5H), 0.37 (d, J=6.5 Hz, 1.5H).
