实验步骤: A solution of 5-(3-aminopropyl)-5H-dibenzo[a,d]cycloheptene (0.75 g., 0.003 mole) in 5 ml. of dry pyridine is treated with 1 ml. of acetic anhydride and then heated to refluxing for 30 minutes. The cooled solution is poured into 100 ml. of water and the oil extracted into benzene. The benzene extract is washed with water, 3N hydrochloric acid, water, and evaporated to dryness under reduced pressure. The 5-(3-acetamidopropyl)-5H-dibenzo[a,d]cycloheptene is obtained as a yellow oily residue weighing 0.87 g. to refluxing for 30 minutes The cooled solution is poured into 100 ml of water and the oil extracted into benzene The benzene extract is washed with water, 3N hydrochloric acid, water evaporated to dryness under reduced pressure

实验步骤: A suspension of platinum oxide (20 mg.) in 2 ml. of absolute alcohol is pre-reduced by shaking with hydrogen in a Hershberg apparatus. A solution of 5-(3-aminopropyl)-5H-dibenzo[a,d]cycloheptene (0.75 g., 0.003 mole) and acetone (0.5 ml.) in 5 ml of absolute alcohol is added and the mixture shaken with hydrogen in a Hershberg apparatus until the hydrogen uptake is complete. Catalyst is filtered through a mat of diatomaceous earth and washed with absolute alcohol. The combined filtrate and washings are evaporated to dryness on the steam-bath under reduced pressure. The residual oily base is dissolved in absolute alcohol and treated with a solution of dry hydrogen chloride in absolute alcohol. The white crystalline 5-(3-isopropylaminopropyl)-5H-dibenzo[a,d]cycloheptene hydrochloride is precipitated by addition of absolute ether in a yield of 0.80 g. (92%), m.p. 234°-236° C. The melting point was unchanged by a further recrystallisation from a mixture of isopropyl alcohol and absolute ether.

实验步骤: 5-(3-Phthalimidopropyl)-5H-dibenzo[a,d]cycloheptene, 2.15 g. (0.0054 mole), is dissolved in 50 ml. of hot 95% ethanol. Hydrazine hydrate, 0.6 ml., is added and the solution heated to refluxing for 2 hours. The solution then is cooled, acidified, and the precipitate of phthalhydrazide removed by filtration. Ethanol is distilled from the filtrate under reduced pressure and the residue dissolved in 40 ml. of water. The filtered solution is evaporated by heating under reduced pressure to a volume of approximately 20 ml. Upon cooling, the hydrochloride salt of 5-(3-aminopropyl)-5H-dibenzo[a,d]cycloheptene is precipitated in a yield of 1.35 g. (87.5%). After recrystallization from a mixture of ethanol and ether and from isopropyl alcohol, an analytical sample melted at 263°-265° C., dec. (0.0054 mole), is dissolved in 50 ml , is added the solution heated to refluxing for 2 hours The solution then is cooled the precipitate of phthalhydrazide removed by filtration Ethanol is distilled from the filtrate under reduced pressure the residue dissolved in 40 ml The filtered solution is evaporated by heating under reduced pressure to a volume of approximately 20 ml Upon cooling the hydrochloride salt of 5-(3-aminopropyl)-5H-dibenzo[a,d]cycloheptene is precipitated in a yield of 1.35 g After recrystallization from a mixture of ethanol and ether
