実験手順

A suspension of Boc-NMe-Tyr(OBn)-OH (0.90 g, 2.3 mmol) and C-(1-phenyl-cyclobutyl)-methylamine hydrochloride (synthesized according to the method in Bridges, A. J., Hamilton, H. W., Moos, W. H., Szotek, D. L., N6−substituted Adenosines, U.S. Pat. No. 4,755,594) (0.46 g, 2.3 mmol) and 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HBTU) (0.97 g, 5.6 mmol) in methylene chloride (10 mL) was treated with DIEA (0.86 mL, 5.1 mmol). The suspension was stirred at room temperature overnight. The resulting solution was concentrated. The residue was taken up in ethyl acetate. The solution was washed with 0.5 M HCl, saturated NaHCO3, dried over MgSO4, filtered, and concentrated. The oil was chromatographed (CH2Cl2:CH3OH 50:1) to give the desired product (1.07 g, 2.02 mmol; 87% yield). MS-APCI 529 (m+1).
