(4-Fluoro-5-isopropyl-2-methoxyphenyl)boronic acid → (4R,5R)-3-[3,5-bis(trifluoromethyl)benzyl]-5-[4'-fluoro-5'-isopropyl-2'-methoxy-4-(trifluoromethyl)biphenyl-2-yl]-4-methyl-1,3-oxazolidin-2-one

Participants

Reaction Steps

Following the procedure described in EXAMPLE 81, 38.5 mg of (4R,5R)-3-[3,5-bis(trifluoromethyl)benzyl]-5-[2-iodo-5-(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one and 18 mg of (4-fluoro-5-isopropyl-2-methoxyphenyl)boronic acid (EXAMPLE 78) gave the title compound. Mass spectrum (ESI) 638.3 (M+1). 1H NMR signals are doubled because of atropoisomerism. 1H NMR (500 MHz, CDCl3): δ 7.55-7.80 (m, 5H), 7.29 (d, J=8 Hz, 1H), 7.00, 6.77 (d, J=8.5 Hz, 1H), 6.68, 6.63 (d, J˜12 Hz, 1H), 5.08, 5.04 (d, J˜5 Hz, 1H), 4.81, 4.75 (d, J=16 Hz, 1H), 4.26, 4.23 (d, 15.5 Hz, 1H), 3.75 (s, 2H), 3.50 (s, 1H), 3.43 (m, 0.5H), 3.12-3.24 (m, 1.5H), 1.24, 1.22 (d, J˜5 Hz, 3H), 1.17, 1.06 (d, J=7 Hz, 3H), 0.84, 0.70 (d, J=6 Hz, 3H).
