Versuchsvorschrift

To a solution of (S)-2-(tert-butoxycarbonyl-methyl-amino)-butyric acid (53.0 mg, 0.24 mmol) in DMA (2 mL) is added HBTU (125.0 mg, 0.33 mmol), HOBt (44.6 mg, 0.33 mmol) and diisopropylethylamine (192 uL, 1.1 mmol). The mixture is stirred at room temperature for 5 minutes. A solution of compound F in DCM (2 mL) is added to the above mixture at 0° C. The reaction mixture is stirred at room temperature for 1 hour and concentrated under vacuum. The residue is diluted with EtOAc. The organic is washed with brine, citric acid (5%), brine, NaHCO3 (Sat.) and brine. The organic layer is then dried and concentrated under vacuum. The crude oil is used directly in the next step without further purification. M+H+=554.
