Procedure

A solution of 70 mg (0.223 mmol) of N-((N-methyl-N-((2-isopropyl-4-thiazolyl)methyl)amino)carbonyl)-L-valine, 79 mg (0.186 mmol) of (2S,3S,5S)-5-amino-2-(N-((5-thiazolyl)methoxycarbonyl)amino)-1,6-diphenyl-3-hydroxyhexane, 30 mg (0.223 mmol) of 1-hydroxybenzotriazole hydrate, and 51 mg (0.266 mmol) of N-ethyl-N'-dimethylaminopropyl carbodiimide in 2 ml of THF was stirred at ambient temperature for 16 h. The resulting solution was concentrated in vacuo, and the residue was purified by silica gel chromatography using 97:3 CH2Cl2 :CH3OH to provide 100 mg (74%) of the desired compound (Rf 0.4, 95:5 CH2Cl2 :CH3OH) as a solid. 1H NMR (d6 -DMSO) δ0.73 (d, J=7 Hz, 6H), 1.30 (d, J=7 Hz, 6H), 1.45 (m, 2H), 1.87 (m, 1H), 2.5-2.7 (m, 4H), 2.87 (s, 3H), 3.23 (heptet, J=7 Hz, 1H), 3.57 (m, 1H), 3.81 (m, 1H), 3.93 (m, 1H), 4.15 (m, 1H), 4.44 (AA', 2H), 4.62 (d, J=6 Hz, 1H), 5.13 (AA', 2H), 6.01 (d, J=9 Hz, 1H), 6.89 (d, J=9 Hz, 1H), 7.1-7.2 (m, 11H), 7.68 (d, J=9 Hz, 1H), 7.85 (s, 1H), 9.05 (s, 1H).
