실험 절차

The nitrile (1.12 g) was dissolved in 60 ml of tetrahydrofuran and 0.80 g of lithium aluminium hydride was added, with cooling to 0° C. under nitrogen. The mixture was allowed to warm to room temperature and was then heated at reflux for 2 hr. The mixture was cooled to room temperature and 10% aqueous tetrahydrofuran was added. The mixture was filtered through anhydrous sodium sulfate and then celite. The filter cakes were washed with a mixture of triethylamine/methanol/ethyl acetate, and the filtrate was concentrated. The residue was purified by flash chromatography (alumina, triethyl amine/methanol/ether) to afford 0.70 g (69%) of 6,12-dimethyl-1,2,3,4,5,6-hexahydro-2,6-methano-9H-pyrrolo[3,2-h][3]benzazocine.
