実験手順
To a solution of 34.3 g of 5,6,7,8,9,10-hexahydro-6,9-methano-benzo[a][8]annulen-11-one (0.184 mol) in 100 mL of pyridine and 100 mL of EtOH was added 29.7 g of hydroxylamine hydrochloride (0.460 mol). The resultant solution was refluxed for 4 hours prior to concentration in vacuo. The residue was partitioned between CH2Cl2 and 10% aqueous citric acid. The aqueous layer was extracted with CH2Cl2 (4×200 mL). The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo to afford the oxime.
