Procedure

In a round bottom flask (25 mL), Fmoc-β-Ala-Ile-Ala-Leu-OBn SEQ ID NO: 119 (0.7 g, 1.0 mmol) is dissolved in 5 mL of anhydrous DMF. Piperidine (1.2 mL, 12.1 mmol) is added to the solution and the mixture is stirred at room temperature for 25 minutes. The reaction is quenched with water (6 mL) and extracted with ethyl acetate (2×10 mL). The combined organic layer is further washed by water (2×5 mL), brine (5 mL) and dried over sodium sulfate. A white solid (0.8 g) is obtained after removal of solvent.
