실험 절차

To a stirred solution of 1.68 g of cyanogen bromide and 35 ml of chloroform was added, at room temperature with stirring under nitrogen, a solution of 3.8 g of 10-chloro-1,2,3,4,5,6-hexahydro-3,6,12-trimethyl-2,6-methano-9H-pyrrolo[3,2-h][3]-benzazocine and 100 ml of chloroform. The mixture was heated at reflux for 2 hr, under nitrogen, and cooled to room temperature. Dilute aqueous sodium bicarbonate solution was added and the layers separated. The organic layer was extracted with dilute aqueous sodium bicarbonate solution. The combined aqueous layers were extracted with ether and the combined organic layers were washed with brine, dried over anhydrous potassium carbonate and filtered. The filtrate was concentrated and the residue was purified by flash column chromatography (silica gel, 2% triethylamine/ethyl acetate) to afford 6.41 g (78%) of 10-chloro-3-cyano-6,12-dimethyl-1,2,3,4,5,6-hexahydro-2,6-methano-9H-pyrrolo-[3,2-h][3]benzazocine.
