A solution of (S)-1-(2′-(trifluoromethyl)-[3,4′-bipyridin]-6-yl)ethanamine (27 mg, 0.10 mmol), (R)-4-((S)-1-fluoroethyl)-3-(2-fluoropyrimidin-4-yl)oxazolidin-2-one (23 mg, 0.10 mmol) and DIPEA (52.4 μl, 0.30 mmol) in DMSO (500 μl) was heated at 110° C. for 1 hr. The solution was then cooled to rt and RP-HPLC purification (acetonitrile:water) provided the 32 mg of the major product as a white solid. 1H NMR (400 MHz, MeOD) δ 8.98 (s, 1H), 8.79 (d, J=5.1 Hz, 1H), 8.23 (dd, J=8.2, 2.4 Hz, 1H), 8.17 (br s, 1H), 8.17-8.12 (m, 1H), 7.98 (dd, J=5.1, 1.7 Hz, 1H), 7.59 (d, J=8.3 Hz, 1H), 7.40 (d, J=5.8 Hz, 1H), 5.11 (br s, 1H), 4.69 (br d, J=27.2 Hz, 1H), 4.55-4.12 (m, 3H), 1.60 (d, J=7.1 Hz, 3H), 1.03 (br s, 3H); HRMS (B) m/z 477.1699 (M+H)+.
