Potassium Carbonate → N-[(3S)-1-[2-fluoro-4-[(5S)-5-[(isoxazol-3-ylamino)methyl]-2-oxo-oxazolidin-3-yl]phenyl]pyrrolidin-3-yl]-2-hydroxy-acetamide

Participants

Reaction Steps

3-(4-(3(S)-Acetoxyacetamidopyrrolidin-1-yl)-3-fluorophenyl)-5(S)-(3-isoxazolylaminomethyl)oxazolidin-2-one (105 mg, 0.23 mM) and potassium carbonate (300 mg, 2.2 mM) were stirred at ambient temperature under nitrogen in methanol (20 ml) for 20 minutes. The mixture was evaporated to dryness and triturated with water (10 ml) to gave the desired product (77 mg ). NMR (DMSO-d6) δ: 1.83 (hextet, 1H); 2.14 (hextet, 1H); 3.20 (m, 1H); 3.29 (m overlapped by H2O, ˜1H); 3.42 (t overlapping m, 3H); 3.49 (m, 1H); 3.75 (dd, 1H); 3.82 (s, 2H); 4.07 (t, 1H); 4.37 (m, 1H); 4.83 (m, 1H); 5.37 (br, 1H); 6.00 (d, 1H); 6.51 (t, 1H); 6.75 (t, 1H); 7.10 (dd, 1H); 7.41 (dd, 1H); 7.85 (d, 1H); 8.37 (d, 1H). MS (ESP): 420 (MH+) for C19H22FN5O5
