Reaction Steps

(R)-4-((S)-1-fluoroethyl)-3-(2-fluoropyrimidin-4-yl)oxazolidin-2-one (50 mg, 0.218 mmol) and (S)-1-(5-(2-fluoro-3-(trifluoromethyl)phenyl)pyrimidin-2-yl)ethanamine (75 mg, 0.262 mmol) were taken up in 3 mL DMSO. Hunig's base (57 uL, 0.327 mmol) was added. The mixture was heated to 110 C for 1.5 h. The reaction mixture was poured into 30 mL water, and extracted with EtOAc (2×30 mL). Organics were washed with 20 mL each water, and brine. Combined organics were dried over Na2SO4, filtered and concentrated on silica gel. Column chromatography (25-100% EtOAc/heptane) gave 82 mg white solid. 1H NMR (400 MHz, CDCl3) δ 8.91 (d, J=1.4 Hz, 2H), 8.25 (d, J=5.7 Hz, 1H), 7.79-7.61 (m, 2H), 7.52 (d, J=5.7 Hz, 1H), 7.44 (tt, J=7.7, 0.8 Hz, 1H), 6.12 (s, 1H), 5.32 (s, 1H), 5.08 (br s, 1H), 4.80 (dddd, J=26.5, 9.1, 3.4, 1.5 Hz, 1H), 4.58 (dd, J=8.8, 3.4 Hz, 1H), 4.44 (td, J=9.0, 1.3 Hz, 1H), 1.68 (d, J=8.8 Hz, 3H), 1.43-1.24 (m, 3H). HRMS (A) m/z 495.1611 (M+H)+. Anal. RP-HPLC tR=3.68 min. Purity 96%/100%.
