실험 절차

TBTU (0.016 g, 0.050 mmol) was 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 (0.020 g, 0.037 mmol) and NMM (0.012 ml, 0.109 mmol) in DMF (2 ml) at 30° C. After 30 min, 2,2-diphenylglycine (0.009 g, 0.037 mmol, 98%) was added and the mixture was stirred at 30° C. for 2.5 h. The reaction was quenched with water (0.2 ml) and the mixture was diluted with MeOH (2 ml). NaBH4 (0.020 g, 0.529 mmol) was added and the mixture was stirred for 10 min. Ammonium acetate buffer (0.1M, 3 ml) was added and most of the methanol was removed under reduced pressure. The remaining solution was purified by preparative HPLC, using a gradient of 20-50% MeCN in 0.1M ammonium acetate buffer as eluent. After freeze-drying, the title compound (0.012 g, 44% yield) was obtained as a white solid. M/z: 752.0. 1H NMR (DMSO, 400 MHz): δ 2.83-2.95 (m, 2H), 3.75 (d, 2H), 4.24-4.28 (m, 1H), 4.54 (s, 1H), 4.68-4.75 (m, 1H), 5.02-5.06 (m, 1H), 6.95-7.03 (m, 2H), 7.04-7.38 (m, 20H), 8.43-8.51 (m, 1H), 8.90 (s, 1H).
