实验步骤: To a stirred suspension of sodium hydride (0.9 g, 37.5 mmole) in dimethylformamide (50 mL) was added azocan-2-one (3.83 g, 30 mmole). The mixture was stirred at room temperature for 15 minutes, and then 5-bromo-1-pentene (5.03 g, 33.7 mmole) was added slowly. The reaction mixture was stirred at room temperature for 30 minutes, and then at 80° C. for 16 hours. The solvent was removed under reduced pressure and water was added to the residue. The mixture was extracted with ethyl ether, the organic phase was washed with water, dried (magnesium sulfate) and concentrated to give 1-pent-4-enyl-azocan-2-one (5.53 g,) as an oil. The reaction mixture was stirred at room temperature for 30 minutes at 80° C. for 16 hours The solvent was removed under reduced pressure and water was added to the residue The mixture was extracted with ethyl ether the organic phase was washed with water dried (magnesium sulfate) concentrated

实验步骤: Phosphorus oxychloride (6.13 g., 0.04 mole) is added in one portion to a stirred mixture of 2-azacyclooctanone (5.1 g., 0.04 mole) and N-phenylphenethylamine (7.9 g., 0.04 mole) in 100 ml. of 1,2-dichloroethane. The mixture is stirred for 16 hr., poured into crushed ice and made basic with 10 N potassium hydroxide. The 1,2-dichloroethane layer is separated, washed with 100 ml. of 1.5 N hydrochloric acid and then with a 100 ml. portion of water. After drying over magnesium sulfate, the 1,2-dichloroethane fraction is concentrated under reduced pressure to provide 10.6 g. of residue which is stirred with water, extracted with ether and then made basic with potassium hydroxide and again extracted with ether. The ethereal extract of the basic mixture is dried (magnesium sulfate) and concentrated under reduced pressure. Distillation of the resulting residue yields 3.5 g., b.p. 152°-170° C/0.15 mm. Hg. of the azocine product free base. The free base is converted to the hydrochloride in ethanol by the addition of ethanolic hydrogen chloride and is recovered by addition of ether affording analytically pure 3,4,5,6,7,8-hexahydro-2-(N-phenylphenethylamino)azocine hydrochloride hemihydrate, m.p. 165°-168° C. (corr.). , poured into crushed ice The 1,2-dichloroethane layer is separated washed with 100 ml After drying over magnesium sulfate the 1,2-dichloroethane fraction is concentrated under reduced pressure to provide 10.6 g extracted with ether again extracted with ether The ethereal extract of the basic mixture is dried (magnesium sulfate) concentrated under reduced pressure Distillation of the resulting residue yields 3.5 g is recovered by addition of ether affording analytically pure 3,4,5,6,7,8-hexahydro-2-(N-phenylphenethylamino)azocine hydrochloride hemihydrate, m.p. 165°-168° C.

实验步骤: To 28.3 g (0.223 mole) of an enantholactam in 250 ml of benzene is added 34.1 g (0.223 mole) of phosphorous oxychloride over 30 minutes. The mixture is stirred at room temperature for 4 hours after which 41.2 g (0.223 mole) of dodecylamine is added. The reaction mixture is stirred at room temperature for 1 hour and refluxed for 4 hours then allowed to stand overnight. The resulting precipitate is washed with benzene, and the benzene wash is extracted with aqueous 2 N hydrochloric acid and combined with the precipitate. The combined fractions are made alkaline with 2N sodium hydroxide, extracted into ether-methylene chloride, dried and recrystallized from isopropyl alcohol to give 2-dodecyliminooctahydroazocine. is added refluxed for 4 hours to stand overnight The resulting precipitate is washed with benzene the benzene wash is extracted with aqueous 2 N hydrochloric acid extracted into ether-methylene chloride dried recrystallized from isopropyl alcohol
