PROCEDURE
实验过程
[2-Oxo-1-phenyl-2-(2-{5-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-imidazol-2-yl}-pyrrolidin-1-yl)-ethyl]-carbamic acid methyl ester (204 mg, 0.385 mmol), (1-{2-[5-(5-Bromo-3a,6a-dihydro-thieno[3,2-b]thiophen-2-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-2-methyl-propyl)-carbamic acid methyl ester (137 mg, 0.268 mmol), Pd(PPh3)4 (31 mg, 0.0268 mmol) and K2CO3 (2M in H2O, 0.4 mL, 0.8 mmol) were combined in 1,2-dimethoxyethane (2.7 mL). After 10 min of degassing with bubbling N2, the reaction mixture was heated to 85° C. for 19 h. After this period, it was cooled and diluted MeOH. The suspension was filtered over a thiol SPE cartridge to remove the palladium, then concentrated. The crude residue was purified by HPLC to afford the title compound (103 mg, 46%). MS (ESI) m/z 835 [M+H]+.
