실험 절차

Triethylamine (2.09 mL, 15 mmol) was added with stirring to a solution of 2,4,5-trifluorobenzoyl chloride (1.95 g, 10 mmol) and ethyl 3-dimethylaminoacrylate 20 (1.43 g, 10 mmol) in 1,4-dioxane (20 mL). The mixture was stirred at r.t. overnight, and solvent was removed under vacuum. The residue was dissolved in ethyl ether (100 mL) and hexanes (20 mL), and the resulting mixture was washed with water (2×100 mL), 2% aq. citric acid (2×100 mL), brine (100 mL), 2.5% aq. NaHCO3 (2×100 mL), and brine (100 mL). The organic layer was dried (MgSO4), and the solvents removed under vacuum to provide ethyl-2-(dimethylamino)methylene-2-(2,4,5-trifluorobenzoyl)acetate 21 as a light orange oil (Yield 2.55 g (85%). MS (m/z): 302 [M+H]+. Rt 4.9 min.). A solution of Compound 21 (0.301 g, 1.0 mmol) and 5-(S)-acetamidomethyl-3-(4-amino-3-fluorophenyl)-oxazolidine-2-one (0.267 g, 1.0 mmol) in EtOH (9 mL) was agitated at 40° C. for 16 h. The solvent was removed under vacuum, and the resulting residue dissolved in ethyl ether (75 mL). The ether solution was washed with 3% aq. citric acid (2×40 mL), brine (40 mL), and dried (MgSO4). The solvent was removed under vacuum to afford Compound 22 as a thick light-orange oil. Yield 0.50 g (90%). MS (m/z): 524 [M+H]+. Rt 5.5 min.
