実験手順

A solution of 4-(1,1,1-trifluoropropan-2-yl)oxazolidin-2-one (270 mg, 1.474 mmol) and 2,4-difluoropyrimidine (171 mg, 1.474 mmol, 1 eq) in DMF (4 mL) was treated with NaH (60%, 88 mg, 2.212 mmol, 1.5 eq), then the resulting mixture was stirred at 0° C. for 10 minutes, then room temperature for 1 h. The reaction mixture was quenched with sat. Na2SO4 (15 mL) diluted with EtOAc (20 mL), washed and 4% aqueous NaCl (3×20 mL), dried over Na2SO4, concentrated in vacuo. Flash column chromatography (silica, 120 g, 15 m) 5% EtOAc/DCM to provide 3-(2-fluoropyrimidin-4-yl)-4-(1,1,1-trifluoropropan-2-yl)oxazolidin-2-one (100 mg, white solid). 1H NMR (400 MHz, CDCl3) δ 8.55 (dd, J=5.8, 2.1 Hz, 1H), 8.20 (dd, J=5.8, 3.7 Hz, 1H), 5.04-4.84 (m, 1H), 4.68 (dd, J=9.5, 2.6 Hz, 1H), 4.54 (t, J=9.2 Hz, 1H), 3.34 (ddddd, J=13.3, 9.3, 7.1, 3.9, 1.6 Hz, 1H), 1.29 (d, J=7.3 Hz, 3H).
