실험 절차

To adamantan-1-yl-methylamino-acetic acid (0.447 g, 2.0 mmol, from Reference Example 6) in dichloromethane (17 mL) is added PyBOP (1.04 g, 2.0 mmol). After 15 min ethyl (2E,4S)-2,5-dimethyl-4-[methyl(3-methyl-L-valyl)amino]hex-2-enoate (0.625 g, 2.0 mmol, WO 99/32509) in dichlormethane (5 mL) is added, followed by diisopropylethylamine (0.75 mL, 4.3 mmol). This is stirred at room temperature overnight. The reaction mixture is evaporated in vacuo and the residue treated with ethyl acetate and water. The ethyl acetate layer is dried over sodium sulfate and purified by hplc. The two diastereomers are partially separated. The first isomer is assigned the SSS configuration and contained 33.4% of the RSS isomer. MS: m/z 518.3 (M+1). The second isomer is assigned the RSS configuration and contained 8.9% of the SSS isomer. MS: m/z 518.3 (M+1).
