실험 절차

To a solution of sodium metal (20 mg) in methanol (30 ml) was added the R(+)-enantiomer of [(5,6-dichloro-2,3,9,9a-tetrahydro-3-oxo-9a-propyl-1H-fluoren-7-yl)oxy]acetonitrile (1.0 g, 2.9 mMole). The reaction mixture was stirred for 1-1/2 hours in a dry nitrogen atmosphere then treated with dimethylamine hydrochloride (475 mg, 5.8 mMole) and stirring was continued for 21/2 hours. The methanol was evaporated in vacuo, the residue was dissolved in water, treated with 10N NaOH (1 ml), extracted with diethyl ether containing 10% tetrahydrofuran, washed with water and brine, dried over potassium carbonate and evaporated in vacuo. The residue was dissolved in a mixture of ethanol and diethyl ether, treated with ethanolic HCl, filtered under nitrogen and washed with diethyl ether to give 0.8 g of the R(+)-enantiomer of N,N-dimethyl-2-[(5,6-dichloro-9a-propyl-3-oxo-2,3,9,9a-tetrahydro-1H-fluoren-7-yl)oxy]ethanimidamide hydrochloride hemihydrate.
