실험 절차

To a solution of 2-(4-bromo-2,6-difluorobenzylthio)-5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazole (250 mg, 0.43 mmol, 1.0 eq), N,N-dimethylprop-2-yn-1-amine (0.07 mL, 0.64 mmol, 1.5 eq) and pyrrolidine (0.05 mL, 0.64 mmol, 1.5 eq) in dry, degassed DMF (2 mL) were added PdCl2(dppf)2 (16 mg, 0.022 mmol, 5 mol %) and CuI (8 mg, 0.043 mmol, 10 mol %). The reaction mixture was heated at 80° C. for 16 h, at which time LCMS showed complete consumption of starting material. The mixture was diluted with EtOAc, washed with brine, dried and concentrated. Purification by column chromatography (0 to 15% MeOH/DCM) furnished 238 mg (95% yield) of 3-(4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-3,5-difluorophenyl)-N,N-dimethylprop-2-yn-1-amine as a brown oil: MS (EI): 584 (MH+).
