실험 절차

Pd(Ph3)4 (15 mg, 0.015 mmol) and PdCl2(Ph3)2 (10 mg, 0.015 mmol) were added to a mixture 2-[5-(7-bromo-9,10-dihydro-phenanthren-2-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carboxylic acid tert-butyl ester (180 mg, 0.37 mmol) and tributyl(1-ethoxyvinyl)tin (0.15 mL, 0.44 mL) in 5 mL dioxane. The reaction mixture was flushed with nitrogen, heated at 80° C. for 16 hours, then cooled to ambient temperature. Water (1.5 mL) and NBS (78 mg, 0.44 mmol) was added and the mixture was stirred at room temperature for 40 minutes, then diluted with ethyl acetate (100 mL). Washed with water and brine, dried over Na2SO4, filtered and concentrated in vacuo. The obtained residue was carried on to next step reaction without purification.
