Versuchsvorschrift

A solution of (1-{2-[5-(4-bromo-phenyl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-2-methyl-propyl)-carbamic acid methyl ester (947 mg, 2.11 mmol), (1-{2-[5-(4-ethynyl-phenyl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-2-methyl-propyl)-carbamic acid methyl ester (1.00 g, 2.53 mmol), and triethylamine (882 μl, 6.33 mmol) in DMF (13 mL) was degassed with N2 gas for 20 minutes. To the degassed solution was added Pd(PPh3)4 (244 mg, 0.21 mmol) and CuI (40 mg, 0.21 mmol). The pressure flask was sealed then heated at 80° C. overnight. After cooling to room temperature, the reaction was concentrated then diluted with EtOAc and washed with water. The aqueous phase was back-extracted two times then the organic phases were combined and dried over Na2SO4. After concentration, the crude material was purified by silica gel chromatography (0-20% MeOH-EtOAc gradient) then reverse phase preparative HPLC (10-85% MeCN—H2O; 0.1% formic acid modifier) to afford [1-(2-{5-[4-(4-{2-[1-(2-methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenylethynyl)-phenyl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester (600 mg, 1.00 mmol, 47% yield). 1H-NMR: 400 MHz, (DMSO-d6) δ: 11.84 (s, 2H), 7.75 (d, 4H), (7.56 (s, 2H), 7.47 (d, 4H), 7.28 (d, 2H), 5.06 (m, 2H), 4.06-4.04 (m, 2H), 3.80 (m, 4H), 3.54 (s, 6H), 2.14 (m, 4H) 2.00-1.90 (m, 6H), 0.89 (d, 6H), 0.84 (d, 6H). LCMS-ESI+: calc'd for C42H51N8O6: 763.4 (M+H+). Found: 763.4 (M+H+).
