实验过程
{4-[(2R,3R)-3-{[(2R)-2-{[tert-butyl(dimethyl)silyl]oxy}-2-(4-fluorophenyl)ethyl]thio}-(4-{3-[(methylsulfonyl)amino]prop-1-yn-1-yl}phenyl)-4-oxoazetidin-2-yl]phenoxy}acetic acid (Method 8) (25.1 mg, 0.040 mmol) was dissolved in DMF (1 ml, dry). N-methylmorpholine (13 μl, 121 mmol) was added and the reaction mixture was stirred at 30° C. for five minutes. TBTU (20.1 mg, 0.063 mmol) was added and the reaction mixture was stirred at 30° C. for 1 hour. Glycyl-3-cyclohexyl-D-alanine (12.5 mg, 0.055 mmol) was added and the reaction mixture was stirred for 2 hours. The reaction mixture was purified with preparative HPLC on a C8 column. A gradient from 10 to 100% MeCN in 0.1M NH4OAc buffer was used as eluent. Most of the MeCN was removed under reduced pressure. The residue was diluted with water and lyophilised to give the title compound, M/z: 921 (M−1).
