Procedure

To a solution of the compound from Step 1 (0.434 g, 2 mmol) in methylene chloride (10 mL) was added Cbz-His(Trt)-OH (1.062 g, 2 mmol), triethylamine (0.8 mL, 5.7 mmol) and HBTU (0.758 g, 2 mmol) dissolved in acetonitrile (10 mL). The reaction mixture 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. Chromatography was carried out on silica gel, using 30% hexanes in ethyl acetate as eluent, to give an oil; 1.38 g (94% yield). MS-APCI: M+1=732.
