Procedure

{1-[4-(4-Bromo-phenyl)-1′-(2,2,2-trifluoro-ethyl)-1′,2′,4′,5′-tetrahydro-1H-[2,4′]biimidazolyl-3′-carbonyl]-2-methyl-propyl}-carbamic acid methyl ester (13.0 mg, 0.0244 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 (12.1 mg, 0.0244 mmol) under an argon atmosphere. Potassium carbonate (6.7 mg, 0.048 mmol) and Pd(PPh3)4 (2.7 mg, 0.0024 mmol) were added, followed by DME (2.0 mL) and water (0.4 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′-(2,2,2-trifluoro-ethyl)-1′,2′,4′,5′-tetrahydro-1H-[2,4′]biimidazolyl-3′-carbonyl]-2-methyl-propyl}-carbamic acid methyl ester (6.1 mg, 0.006 mmol) as the TFA salt: LCMS-ESI+: calc'd for C41H50F3N9O6: 821.8 (M+). Found: 823.4 (M+H+); 1H-NMR: 300 MHz, (MeOH-d4) δ: 7.89-7.82 (m, 10H), 5.39 (dd, J=6.3, 6.3 Hz, 1H), 5.25 (m, 1H), 4.78 (d, J=6.9 Hz, 1H), 4.24 (d, J=7.5 Hz, 1H), 4.10 (m, 1H), 4.00 (d, J=7.5 Hz, 1H), 3.88 (m, 1H), 3.67 (s, 3H), 3.66 (s, 3H), 3.65-3.43 (m, 4H), 2.58 (m, 1H), 2.29-2.01 (m, 5H), 1.03-0.89 (m, 12H).
