实验步骤: By substituting 5-(3-dimethylaminopropyl)-3-methylsulfonyl-5H-dibenzo[a,d]cycloheptene for the 5-(3-dimethylaminopropylidene)-5H-dibenzo[a,d]cycloheptene of Example 6, Step A., and following substantially the same procedure described in Example 6, Steps A and B., there is obtained 5-(3-methylaminopropyl)-3-methylsulfonyl-5H-dibenzo[a,d]cycloheptene as an oily residue. The base is converted to the hydrogen oxalate salt by treating an ethanolic solution of the base with a 10% excess of oxalic acid in ethanol. Dilution with absolute ether precipitates 5-(3-methylaminopropyl)-3-methylsulfonyl-5H-dibenzo[a,d]cycloheptene hydrogen oxalate as a white crystalline solid, m.p. 114°-119° C. dec. An analytical sample melts at 114°-115° C. dec. after two recrystallizations from mixtures of absolute ethanol and absolute ether.

实验步骤: A solution of 23.06 g. (0.0834 mole) of 5-(3-dimethylaminopropylidene)-5H-dibenzo[a,d]cycloheptene in 61 ml. of benzene is added dropwise to a stirred solution of 9.80 g. (0.0917 mole) of cyanogen bromide in 38 ml. of benzene. Some heat is evolved. The mixture is stirred for 3 hours at room temperature, and filtered to remove any precipitate which forms. The filtrate, together with a benzene wash of the precipitate, is evaporated to dryness on a steam-bath under reduced pressure to remove excess cyanogen bromide and solvent. The residual crude cyanamide is dissolved in benzene, and the solution is washed with dilute hydrochloric acid to remove any unchanged amine, then with water. The benzene solution is then evaporated under reduced pressure leaving 5-[3-N-cyano-N-methyl)aminopropylidene]-5H-dibenzo[a,d]cycloheptene as a yellow oil weighing typically 19.6 g. filtered to remove any precipitate which The filtrate, together with a benzene wash of the precipitate is evaporated to dryness on a steam-bath under reduced pressure to remove excess cyanogen bromide and solvent The residual crude cyanamide is dissolved in benzene the solution is washed with dilute hydrochloric acid to remove any unchanged amine The benzene solution is then evaporated under reduced pressure
