실험 절차

Diisopropylethylamine (4.67 ml, 0.0268 mol) is added to a mixture of 4-(5(R)-Azidomethyl-2-oxo-oxazolidin-3-yl)-2-fluorobenzoic acid (2.50 g, 0.00892 mol) [prepared according to the procedure described in U.S. Pat. No. 6,239,152] and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (3.73 g, 0.00981 mol) in DMF (30 ml) and stirred for 20 minutes at room temperature. tert-Butyl carbazate (1.30 g, 0.00981 mol) is then added and the mixture stirred at room temperature overnight. The reaction mixture is evaporated under vacuum and the residue diluted with water. The resulting precipitate is filtered and dried under vacuum to give product as a white solid (3.52 g, 99%); 1HNMR (300 MHz, DMSO-d6) δ 1.42 (s, 9H), 3.72-3.76 (m, 2H), 3.81 (dd, J=6.0, 9.3 Hz, 1H), 4.17 (t, J=9.1 Hz, 1H), 4.88-4.96 (m, 1H), 7.43 (dd, J=2.2, 8.8 Hz, 1H), 7.57 (dd, J=2.2, 13.2, 1H), 7.66 (t, J=8.2, 1H), 8.96 (s, 1H), 9.92 (s, 1H); Rf(EtOAc)=0.54; mp 173-5.
