実験手順

To a solution of {4-[(2R,3R)-3-{[2-(1,3-benzodioxol-5-yl)-2-oxoethyl]thio}-1-(4-methylphenyl)-4-oxoazetidin-2-yl]phenoxy}acetic acid (0.020 g, 0.040 mmol) and NMM (0.013 ml, 0.116 mmol) in DMF (3 ml) at RT was added TBTU (0.020 g, 0.062 mmol). The reaction mixture was stirred for 30 min after which glycyl-3-cyclohexyl-D-alanine (0.011 g, 0.032 mmol) was added. The mixture was stirred for 22 h before the reaction was quenched by the addition of water (1 ml). The mixture was diluted with MeOH (2 ml) and added NaBH4 (0.028 g, 0.740 mmol). After 15 min the reaction was quenched by the addition of an aqueous solution of hydrochloric acid (1M, 1 ml) and most of the methanol was removed under reduced pressure. The remaining solution was purified by preparative HPLC using a gradient of 20-60% MeCN in a 0.1M ammonium acetate buffer as eluent. Freeze-drying of the pure fractions gave the desired product.
