実験手順

To a stirred solution of methyl 2-bromo-5-((5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluoro-3-methoxyphenyl)-1H-imidazol-2-ylthio)methyl)benzoate (506 mg, 0.79 mmol, 1.0 eq), propargyl alcohol (0.07 mL, 1.2 mmol, 1.5 eq) and pyrrolidine (0.1 mL, 1.2 mmol, 1.5 eq) in dry, degassed DMF (4 mL) was added PdCl2(dppf)2 (30 mg, 0.04 mmol, 5 mol %) and CuI (15 mg, 0.08 mmol, 10 mol %). The reaction mixture was heated at 80° C. for 5 h at which time LCMS showed 85% conversion. The mixture was diluted with EtOAc, washed with brine, dried and concentrated. Purification by column chromatography (0 to 75% EtOAc/Hexanes) provided 378 mg (78% yield) of methyl 5-((5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluoro-3-methoxyphenyl)-1H-imidazol-2-ylthio)methyl)-2-(3-hydroxyprop-1-ynyl)benzoate. MS (EI) m/z 615 (MH+).
