실험 절차

HOBt (4 equivalents, 540 mg, 4 mmol), N-methylmorpholine (3 equivalents, 3 mmol), N-tert-butoxycarbonyl-D-leucine (1.0 equivalent, 230 mg, 1 mmol; Bachem), EDC (2 equivalents, 380 mg, 2 mmol) and again N-methylmorpholine (2 equivalents, 2 mmol) are added successively at −10° C. to a solution of L-leucine benzyl ester hydrochloride (1.1 equivalents, 300 mg, 1.1 mmol; cf. T. Wakamiya, M. Kamata, S. Kusumoto, H. Kobayashi, Y. Sai, et al., Bull. Chem. Soc. Jpn., 1998, 71, 699-710) in dichloromethane p.a. (30 ml). The reaction mixture warms slowly (about 12 h) to RT, whereby complete conversion of the amine component is observed by means of HPLC. The reaction mixture is concentrated in vacuo, taken up in acetonitrile and purified by means of preparative HPLC (Method 13). 362 mg (80% of theory) of the title compound are obtained.
