PROCEDURE
实验过程
4-(4-Bromo-phenyl)-3′-(2-methoxycarbonylamino-3-methyl-butyryl)-2′,3′,4′,5′-tetrahydro-1H-[2,4′]biimidazolyl-1′-carboxylic acid tert-butyl ester (75 mg, 0.136 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 (67.6 mg, 0.136 mmol) under an argon atmosphere. Potassium carbonate (37.5 mg, 0.272 mmol) and Pd(PPh3)4 (15.7 mg, 0.014 mmol) were added, followed by DME (3 mL) and water (0.6 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 (55 mg): LCMS-ESI+: calc'd for C44H57N9O8: 839.9 (M+). Found: 840.5 (M+H+); 1H-NMR: 300 MHz, (MeOH-d4) δ: 7.90-7.81 (m, 10H), 5.58 (m, 1H), 5.43 (m, 1H), 5.25-5.20 (m, 2H), 4.24 (d, J=7.5 Hz, 1H), 4.11 (m, 1H), 3.99 (m, 1H), 3.86 (m, 2H), 3.67 (s, 3H), 3.66 (s, 3H), 3.46 (d, J=7.2 Hz, 1H), 2.59 (m, 1H), 2.22-2.10 (m, 5H), 1.53 & 1.44 (s, 9H) 1.04-0.89 (m, 12H).
