Procedure
Methyl chloroformate (0.097 ml, 1.26 mmol) is added dropwise to 5-(5-aminomethyl-2-oxo-oxazolidin-3-yl)-7-fluoro-1-isopropyl-1,3-dihydro-indol-2-one (21, 0.355 g, 0.842 mmol) and diisopropylethylamine (0.616 ml, 3.37 mmol) in dichloromethane (4 ml) at 0° C. The reaction is stirred at 0° C. for 30 minutes and then allowed to warm at room temperature. The reaction mixture is diluted with dichloromethane, washed with water, citric acid and brine, dried (Na2SO4) and evaporated. The residue is purified to give the title compound as a solid. HPLC r.t. 4.42 min; 1H NMR (300 MHz, CDCl3) δ7.33 (d, J=1.2 Hz, 1H), 7.24 (dd, J=2.1, 14 Hz, 1H), 5.14 (br s, 1H), 4.80-4.92 (m, 1H), 4.75-4.84 (m, 1H), 4.05 (t, J=8.7 Hz, 1H), 3.81 (dd, J=6.6, 9 Hz, 1H), 3.71 (s, 3H), 3.57 (s, 2H), 3.52-3.65 (m, 2H), 1.44 (d, J=6.9 Hz, 6H); MS for C17H20FN3O5 m/z 366 (M+H)+.
