Versuchsvorschrift

The product from Step 1 (0.67 g, 2.5 mmol) was dissolved in methylene chloride (10 mL) and Cbz-His(Trt)-OH (1.46 g, 2.75 mmol) was then added, followed by diisopropylethylamine (1.3 mL, 7.5 mmol), HATU (1.05 g, 2.76 mmol), HOAt (0.374 g, 2.75 mmol), and dimethylformamide (10 mL). The reaction was stirred overnight at room temperature. The solution was concentrated, the residue taken up in ethyl acetate and washed three times with saturated NaHCO3, brine, dried over MgSO4, filtered and concentrated in vacuo to give a white solid; 1.8 g (97% yield). MS-APCI: M+1=747.
