Procedure

{1-[4-(4-Bromo-phenyl)-1′-phenyl-1′,2′,4′,5′-tetrahydro-1H-[2,4]biimidazolyl-3′-carbonyl]-2-methyl-propyl}-carbamic acid methyl ester (40 mg, 0.076 mmol) was combined with [2-Methyl-1-(2-{4-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-propyl]-carbamic acid methyl ester (37.6 mg, 0.076 mmol) under an argon atmosphere. Potassium carbonate (20.9 mg, 0.152 mmol) and Pd(PPh3)4 (8.7 mg, 0.0076 mmol) were added, followed by DME (1.8 mL) and water (0.3 mL). The mixture was heated under microwave conditions for 20 minutes at 120° C. All volatiles were removed in vacuo and the crude material was dissolved in DMF and purified via RP-HPLC (eluent: water/MeCN w 0.1% TFA) to yield the product {1-[5-(4′-{2-[1-(2-Methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-biphenyl-4-yl)-1′-phenyl-1′,2′,4′,5′-tetrahydro-1H-[2,4]biimidazolyl-3′-carbonyl]-2-methyl-propyl}-carbamic acid methyl ester (5.4 mg): LCMS-ESI+: calc'd for C45H53N9O6: 815.9 (M+); Found: 816.5 (M+H+); 1H-NMR: 300 MHz, (MeOH-d4) δ: 7.89-7.86 (m, 10H), 7.35 (m, 2H), 7.18 (m, 1H), 6.94 (m, 2H), 5.67 (m, 1H), 5.37 (m, 1H), 5.25 (m, 1H), 5.12 (m, 1H), 4.31-4.08 (m, 3H), 4.01-3.79 (m, 3H), 3.67 (s, 3H), 3.66 (s, 3H), 2.58 (m, 1H), 2.29-1.99 (m, 5H), 0.99-0.89 (m, 12H).
