To a mixture of N-{[3-(5-chloropyridin-2-yl)-2-oxo-1,3-oxazolidin-5-yl]methyl}-4-(5-cyano-7-isopropyl-1,3-benzoxazol-2-yl)benzamide (52 mg) and potassium carbonate (55 mg) in 1 ml of tetrahydrofuran and 1 ml of water was added 2-trifluoromethoxyphenylboronic acid (82 mg) and palladium di-tert-butylphosphinoferrocene (13 mg). The mixture was heated via microwave for 15 min at 150° C. The sample was cooled to room temperature, and purified was purified via column chromatography on a Biotage Horizon 40M column eluting with 0% ethyl acetate in hexanes (1 column volumes), followed by a gradient to 100% ethyl acetate in hexanes (over 10 column volumes), and held at 100% ethyl acetate for 3 column volumes to provide the title compound as an off-white solid (53 mg, 83%). Mass spectrum (ESI) 642.2 (M+1). 1H NMR (500 MHz, CDCl3): δ 8.43 (s, 1H), 8.35 (d, J=7.8 Hz, 2H), 8.28 (d, J=8.7 Hz, 1H), 7.98 (d, J=8.3 Hz, 2H), 7.94 (s, 1H), 7.84 (d, J=8.7 Hz, 1H), 7.52 (s, 1H), 7.40 (m, 4H), 6.76 (bs, 1H), 4.98 (m, 1H), 4.48 (dd, J=9.1 Hz, 10.7 Hz, 1H), 4.13 (m, 2H), 3.72 (m, 1H), 3.49 (sept, J=6.9 Hz, 1H), 1.46 (d, J=7.1 Hz, 6H).
