Reaction Steps

(R)-3-(2,5-difluoropyrimidin-4-yl)-4-(fluoromethyl)oxazolidin-2-one (105 mg, 0.449 mmol), (S)-1-(5-(4-chlorophenyl)oxazol-2-yl)ethanamine (100 mg, 0.449 mmol), and DIPEA (157 ul, 0.898 mmol) were dissolved in DMSO (1 mL) and the reaction mixture was heated at 120° C. for 2 h. The reaction mixture was cooled, diluted with EtOAc, washed with water and brine, and concentrated in vacuo. Column chromatography (5-50% EtOAc/DCM) gave the desired product (169 mg) as a white foam. 1H NMR (400 MHz, CDCl3) b 8.26 (d, J=2.8 Hz, 1H), 7.59-7.50 (m, 2H), 7.45-7.36 (m, 2H), 7.25 (s, 1H), 5.66 (d, J=7.6 Hz, 1H), 5.21 (br s, 1H), 4.86 (ddddd, J=20.0, 8.6, 7.0, 4.3, 2.8 Hz, 1H), 4.66-4.44 (m, 3H), 4.41 (br s, 1H), 1.71 (d, J=7.0 Hz, 3H). HRMS-Acidic. LC-UV/ESI-MS data was recorded on an Acquity LCTp Tof—Rs(FWHM) >12000 Accuracy <5 ppm. Column: Acquity BEHC18 1.7 μm 2.1×50 mm-50° C.
