Reaction Steps

Methyl chloroformate (0.038 ml, 0.480 mmol) is added dropwise to (R)-5-(5-aminomethyl-2-oxo-oxazolidin-3-yl)-7-fluoro-1-propyl-1,3-dihydro-indol-2-one (0.135 g, 0.320 mmol) and diisopropylethylamine (0.235 ml, 1.28 mmol) in dichloromethane (3 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 and brine, dried (Na2SO4) and evaporated. The residue is purified by PTLC (5% MeOH/DCM) to give the title compound as an off white solid. HPLC r.t. 4.40 min; 1H NMR (300 MHz, CDCl3) 7.30 (m, 1H), 7.21 (m, 1H), 5.10 (t, 1H), 4.77 (m, 1H), 4.02 (t, J=9 Hz, 1H), 3.77-3.82 (m, 3H), 3.68 (s, 3H), 3.57 (s, 2H), 3.49-3.63 (m, 2H), 1.69 (m, 2H), 0.95 (t, J=7.5 Hz, 3H); MS for C17H20F2N3O5 m/z 366.1 (M+H)+.
