실험 절차

To a stirred solution of 3-(2,2,2-trichloroethyloxycarbonylamino)isoxazole (1.30 g, 5.0 mmol), 5(R)-hydroxymethyl-3-(3-fluoro-4-(1-benzyl-1,2,5,6-tetrahydropyrid-4-yl)phenyl)oxazolidin-2-one (WO 97/30995; 1.91 g, 5.0. mmol) and tributylphosphine (1.52 g, 7.5 mmol) in dry tetrahydrofuran (50 ml) under a nitrogen atmosphere at 0° C., was added 1,1′-(azodicarbonyl)dipiperidine (1.89 g, 7.5 mmol) in dry tetrahydrofuran (15 ml). The solution was stirred at 0° C. for 30 minutes before being allowed to come to room temperature and it was then stirred for 2 days. The mixture was filtered, concentrated by rotary evaporation and chromatographed by MPLC (30% ethyl acetate/hexane, ICN Alumina N 32-63), and triturated with ether to give the title compound as a white amorphous solid (1.62 g, 52%). NMR: 2.41 (m, 2H), 2.60 (t, 2H), 3.15 (m, 2H), 3.90 (dd, 1H), 4.18 (m, 2H), 4.37 (dd, 1H), 5.04 (dd, 3H), 5.95 (broad s, 1H), 6.88 (s, 1H), 7.32 (m, 3H), 8.89 (s, 1H); m/z ES+ (M+H)=623.
