Abstract
A high yielding and short process for preparing the 3'-aminomethylnicotine hapten of general formula I permits the isolation of the hapten in very pure quantities. The process can be adapted for the synthesis of a single stereoisomer or mixtures of stereoisomers, such as the stereoisomers trans-Ia and trans-Ib: Compounds of general formula I are useful for the preparation of hapten-carrier conjugates in the treatment of nicotine addiction.
