Versuchsvorschrift

9-1 (32 mg, 0.073 mmol), amino-acetic acid methyl ester (0.11 mmol) and HOBT (15 mg, 0.11 mmol) were combined in DCM (1 mL) and stirred at room temperature for 10 minutes. EDC(19 mg, 0.1 mmol) was added and the mixture was stirred for 18 h. The solution was washed with 2 mL of aqueous NaHCO3, concentrated and taken up with 1 mL of DCM. 1 mL of TFA was added and the mixture was stirred at room temperature for 1 h. It was then concentrated under a stream of nitrogen and purified on preparative HPLC to give 31-1: LC-MS 496.5 (MH).
