실험 절차

N-Methyl morpholine (0.037 g, 0.370 mmol) and TBTU (0.039 g, 0.120 mmol) were added to a solution of N-{[4-((2R,3R)-1-(4-fluorophenyl)-3-{[2-(4-fluorophenyl)-2-oxoethyl]thio}-4-oxoazetidin-2-yl)phenoxy]acetyl}glycine (0.025 g, 0.046 mmol) in DMF (2 ml) at 30° C. After 1 h, 1-aminocyclopropane carboxylic acid (0.019 g, 0.185 mmol) was added. After 1 h, the reaction was quenched by the addition of water (1 ml). After 10 minutes, MeOH (2 ml) and NaBH4 (0.035 g, 0.925 mmol) were added. Full conversion to the corresponding alcohol was obtained after 5 minutes. The reaction was quenched by the addition of 0.1M NH4OAc buffer (2 ml). The product was purified by preparative HPLC (eluent 0-50% CH3CN in 0.1M NH4OAc buffer). Freeze-drying of the pure fractions afforded the title compound (0.045 g, 78%) as a colourless solid. 1H NMR [(CD3)2SO), 400 MH] δ 0.78-0.88 (m, 2H), 1.08-1.22 (m, 2H), 2.84-2.94 (m, 2H), 3.63-3.72 (m, 2H), 4.24-4.29 (m, 1H), 4.48-4.52 (m, 2H), 4.68-4.75 (m, 1H), 5.03-5.06 (m, 1H), 6.96-7.37 (m, 12H), 7.78-8.36 (m, 2H).
