실험 절차

[2-Methyl-1-(1-{5-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-imidazol-2-yl]-cyclopropylcarbamoyl)-propyl}-carbamic acid methyl ester (85 mg, 0.21 mmol) and (1-(2-[5-(4-bromo-phenyl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl)-2-methyl-propyl)-carbamic acid methyl ester (97 mg, 0.21 mmol) in 3:1 DME/H2O (2.5 mL) were treated with Pd(PPh3)4 (10 mg, 0.0084 mmol) and K2CO3 (2 M solution, 0.42 mL, 0.84 mmol). The mixture was stirred in a sealed tube at 80° C. for 3 hours. The mixture was filtered through a fritted glass funnel and concentrated. The mixture was subjected to a reverse phase HPLC column (5-95% MeCN—H2O; 0.1% TFA modifier) to afford (1-{2-[5-(4′-{2-[1-(2-methoxycarbonylamino-3-methyl-butyrylamino)-cyclopropyl]-3H-imidazol-4-yl}-biphenyl-4-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-2-methyl-propyl)-carbamic acid methyl ester (2.3 mg, 2%) as a white solid (TFA salt): 1H NMR (CD3OD, 300 MHz) 7.93 (s, 2H), 7.84 (m, 4H), 5.20 (m, 1H), 4.23 (d, J=7.2 Hz, 2H), 4.01 (m, 2H), 3.83 (m, 4H), 3.70 (s, 3H), 3.66 (s, 3H), 3.38 (m, 2H), 2.57 (m, 2H), 2.18 (m, 4H), 2.04 (m, 4H), 1.75 (m, 4H), 1.58 (m, 4H), 0.95 (m, 12H); MS (ESI) m/z 725 [M+H]+.
