Reaction Steps

10-Chloro-3-cyano-6,12-dimethyl-1,2,3,4,5,6-hexahydro-2,6-methano-9H-pyrrolo[3,2-h][3]benzazocine (6.41 g) was dissolved in 300 ml of tetrahydrofuran, and with stirring, 4.06 g of lithium aluminum hydride was added, under nitrogen. The suspension was heated at reflux for 2 hr and ethyl acetate was added dropwise. To the mixture was added water, 15% aqueous sodium hydroxide solution, and water. The suspension was filtered, and the filtrate was concentrated. The residue was triturated with ether, the mother liquor was concentrated and 2-g portions of the residue were alkylated with phenethyl bromide and 4-bromo-2-methylbut-2-ene according to the procedures described in Examples 23 and 26 to give 0.35 g (20%) and 0.41 g (24%), respectively, of product. Column chromatography (alumina, ether) followed by recrystallization from dichloromethane-ether-pentane afforded the analytical sample, mp 208°-210° C. (dec.).
