Procedure

(S)-{1-[5-(4′-{2-[1-(2-Methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-biphenyl-4-yl)-1H-imidazol-2-yl methyl]-2-oxo-piperidin-3-yl}-carbamic acid tert-butyl ester was prepared following the method described above. C0H50N8O6 calculated 738.4 observed [M+1]+ 739.5; rt=1.80 min. 1H (DMSO-d6): δ=8.09 (s, 1H), 7.90 (m, 8H), 7.30 (d, J=8.4 Hz, 1H), 6.97 (d, J=8.4 Hz, 1H), 5.10 (t, J=7.2 Hz, 1H), 7.85 (d, J=16.4 Hz, 1H), 4.56 (d, J=15.6 Hz, 1H), 4.09 (t, J=8.0 Hz, 1H), 3.99 (m, 2H), 3.82 (m, 2H), 3.51 (s, 2H), 3.43 (t, J=5.6 Hz, 1H), 2.20 (m, 1H), 2.14-1.86 (series m, 9H), 1.34 (s, 9H), 0.810 (m, 6H). The Following (Boc Deportation) Constitutes an Example of Method 804 (R)-{1-[2-(5-{4′42-(3-Amino-2-oxo-piperidin-1-ylmethyl)-3H-imidazol-4-yl]-biphenyl-4-yl}-1H-imidazol-2-yl)-pyrrolidine-1-carbonyl]-2-methyl-propyl}-carbamic acid methyl ester: A solution of hydrogen chloride (4N, 8 mL) in dioxane was added to a solution of (R)-{1-[5-(4′-{2-[1-(2-Methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-biphenyl-4-yl)-1H-imidazol-2-ylmethyl]-2-oxo-piperidin-3-yl}-carbamic acid tert-butyl ester (175 mg, 0.24 mmol) in dichloromethane (2 mL). After 1 hour the solvent was removed under reduced pressure. The resulting residue was placed on a high vacuum for 1 hour to provide (R)-{1-[2-(5-{4′-[2-(3-amino-2-oxo-piperidin-1-ylmethyl)-3H-imidazol-4-yl]-biphenyl-4-yl}-1H-imidazol-2-yl)-pyrrolidine-1-carbonyl]-2-methyl-propyl}-carbamic acid methyl ester. The yield was assumed to be 100% percent. A sample suitable for analysis was obtained by subjection to reverse phase chromatography with an eluent of 0.1% TFA in water and 0.1% TFA in acetonitrile. The product-containing fractions were combined and the solvent was removed by lyophilization. C35H42N8O4 calculated 638.3 observed [M+l]+ 639.4; rt=1.41 min. 1H (DMSO-d6): δ=8.33 (m, 1H), 8.12 (m, 1H), 7.99 (m, 1H), 7.92 (m, 6H), 7.26 (d, J=8.4 Hz, 1H), 5.13 (t, J=8.0 Hz, 1H), 4.83 (m, 2H), 4.09 (t J=8.0 Hz, 1H), 4.09-3.82 (series m, 6H), 2.36 (m, 2H), 2.14 (m, 2H), 1.96 (m, 4H), 0.76 (m, 6H).
