Participants

Reaction Steps

The compound is prepared from {3-[4-(4-oxo-3,4-dihydro-2H-pyridin-1-yl)-phenyl]-2-oxo-oxazolidin-5-ylmethyl}-carbamic acid tert-butyl ester (250 mg, 0.64 mmol) and ethyl difluoroacetate (120 mg, 0.96 mmol) following the method described for Example 5 (using ethyl difluoroacetate as starting agent). The product is purified by silica gel column chromatography (eluent 1% MeOH in EtOAc) and recrystallized from MeOH to provide the title compound. MS (m/z): 366 [M+1]. 1H NMR (300 MHz, DMSO) δ 9.16 (t, J=5.8 Hz, 1H), 7.73 (d, J=8.0 Hz, 1H), 7.53 (d, J=9.1 Hz, 2H), 7.28 (d, J=9.1 Hz, 2H), 6.24 (t, J=53.0 Hz, 1H), 4.98 (d, J=7.7 Hz, 1H), 4.80–4.75 (m, 1H), 4.14 (t, J=9.1 Hz, 1H), 3.97–3.92 (m, 2H), 3.76 (dd, J=6.3 and 9.1 Hz, 1H), 3.52 (t, J=5.5 Hz, 2H), 2.47 (t, J=7.1 Hz, 2H).
