実験手順

1-{2-[5-(9-{2-[1-(2-Methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-6-methyl-6,7-dihydro-5H-dibenzo[c,e]azepin-3-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-2-methyl-propyl)-carbamic acid methyl ester: To the solution of 3,9-bis-[2-(pyrrolidin-2-yl)-3H-imidazol-4-yl]-6-methyl-6,7-dihydro-5H-dibenzo[c,e]azepine (25 mg, 0.035 mmol) and MeOCO-Val-OH (13 mg, 0.074 mmol) in DMF (1.2 ml) was added HATU (28 mg, 0.074 mmol), followed by diisopropylethylamine (61 μl, 0.35 mmol). The mixture was stirred for 90 minutes and was diluted with EtOAc. The organic phase was washed with 1 N NaOH solution, water, and brine, and was dried with sodium sulfate. Concentration and purification by HPLC (0.1% TFA/CH3CN/0.1% TFA/H2O) gave (1-{2-[5-(9-{2-[1-(2-methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-6-methyl-6,7-dihydro-5H-dibenzo[c,e]azepin-3-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-2-methyl-propyl)-carbamic acid methyl ester (24 mg). m/z: 794.3 (M+H)+, 397.8 (M+2H)+/2. 1H NMR (CD3OD, 300 MHz) δ 8.0-7.9 (8H, m), 5.27 (2H, m), 4.3-4.2 (2H, m), 4.2-3.8 (8H, m), 3.66 (6H, s), 3.08 (3H, s), 2.7-2.5 (2H, m), 2.4-1.9 (8H, m), 0.94-0.90 (12H, m).
