  • Patent number: 5663356
    Abstract: Patients susceptible to or suffering from central nervous system are treated by administering an effective amount of an aryl substituted olefinic amine compound, such as (E)-metanicotine. (E)-metanicotine is provided from nicotine. Nicotine is reacted with ethyl chloroformate to produce ethyl N-methyl-N-[4-chloro-4-(3-pyridyl)butyl]carbamate, which then is reacted in the presence of potassium tert-butoxide, tetrahydrofuran and dimethylformamide to produce (E)-metanicotine N-ethyl carbamate, which then is subjected to hydrolysis using hydrochloric acid to produce a reaction mixture containing (E)-metanicotine. The reaction mixture containing (E)-metanicotine is adjusted to a slightly basic pH, and then contacted with dichloromethane. The resulting water immiscible phase then is separated from the aqueous phase. The aqueous phase, then is adjusted to a very basic pH, and then contacted with methyl tert-butyl ether.
