実験手順
Palladium tetrakis(triphenylphosphine) (39 mg, 0.03 mmol) was added to a degassed, ambient temperature solution of 5-bromoisothiazole (55 mg, 0.34 mmol), 2-(4-bromophenyl)-1-[4-(2,2-dimethylpropyl)-1-trityl-1H-imidazol-2-yl]propan-2-ol (200 mg, 0.34 mmol) and hexamethylditin (110 mg, 0.34 mmol) in 1,4-dioxane (15 mL). After stirring at 90° C. for 16 h, the reaction mixture was diluted with water and extracted with ethyl acetate and methylene chloride. The combined organic extracts were concentrated in vacuo. Chromatography over silica eluting with 0-50% ethyl acetate/hexane afforded 1-[4-(2,2-dimethylpropyl)-1-trityl-1H-imidazol-2-yl]-2-(4-isothiazol-5-ylphenyl)propan-2-ol.
