실험 절차

0.12 g of sodium cyanate and 0.22 ml of trifluoro-acetic acid were added to a solution of 0.5 g of 5-(2-amino-ethoxy)-7-chloro-1-[2-methoxy-4-(2-chlorobenzoylamino)-benzoyl]-2,3,4,5-tetrahydro-1H-benzoazepine dissolved in 15 ml of dry dimethylformamide. The mixture was stirred at 80° C. for 1 hour. After cooling, the reaction mixture was mixed with slight amounts of a saturated aqueous sodium hydrogen-carbonate solution and hexane, followed by extraction with ethyl acetate. The organic layer was water-washed, then dried over magnesium sulfate and subjected to vacuum distillation to remove the solvent. The residue was recrystallized from acetone-n-hexane to obtain 0.41 g (76%) of 5-(2-ureidoethoxy)-7-chloro-1-[2-methoxy-4-(2-chloro-benzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzoazepine.
