Versuchsvorschrift

To a solution containing Cbz-Tle-OH.DCHA salt (4.1 g, 9.0 mmol) and HATU (3.8 g, 10 mmol) in NMP (50 mL) was added NMM (1.5 mL), followed by a solution of crude 22 (2.6 g, 7.5 mmol) in NMP (50 mL) at room temperature. The reaction mixture was stirred at room temperature. After 16 h, the reaction mixture was diluted with 10% EtOAc in Et2O, washed successively with water, 1N HCl, 1N NaOH, and brine, dried over anhydrous Na2SO4, filtered, and concentrated. The crude residue was purified by RP-HPLC (2″ Dynamax® C18; 10-100% ACN/water containing 0.1% HOAc over 30 min; Flow: 40 mL/min) to afford 3.5 g of 23 as white foam. Mass spectrum, m/z [688.3] (M+H)+.
