실험 절차

1.74 (3.16 mmol) of tert-butyl 3-(tert-butoxycarbonylphenylmethyl)-5-iodo-2-oxo-2,3-dihydrobenzimidazole-1-carboxylate (XIIb) were dissolved in 20 ml of dry DMF and stirred under a stream of nitrogen for 20 min. 482 mg (4.11 mmol) of zinc(II) cyanide and 292 mmol (0.25 mmol) of Pd[P(Ph)3]4 were added, and the reaction solution was stirred at 80° C. for 1.5 h. The cooled reaction solution was mixed with 70 ml of water and extracted with ethyl acetate (3×). The combined organic phases were washed with saturated NaCl solution and dried over magnesium sulfate, and the solvent was removed in vacuo. The residue was purified by chromatography on silica gel (mobile phase gradient 10-30% ethyl acetate in cyclohexane). Yield: 1.08 g (76%) of white solid
