    Description / Table of Contents: Labelled Tropane Alkaloids, VI1). - Syntheses of [N-Methyl-T1] Psicain-neu and of Polytopically Tritiated PsicainThe reaction of norpsicain-neu (3) WITH cth2I yielded [N-methyl-T1] Psicain-neu (4), isolated as hydrochloride (activity 51.65 mCi/mmol). Polytopic tritiation of psicain (2) by a modified Wilzbach method yielded a product which was also isolated as hydrochloride with an activity of 30.8 mCi/mmol. The distribution of tritium in [3H]psicain in the benzoic acid, in the pseudoecgonine, and in the CH3O group was 84.5: 11.5:4 per cent.
    Notes: Durch Umsetzung von Norpsicain-neu (3) mit CTH2J wurde [N-Methyl-T1]Psicain-neu (4) dargestellt und als Hydrochlorid isoliert (Aktivität 51.65 mCi/mmol). Die polytope Tritiierung von Psicain (2) nach einer modifizierten Wilzbach-Methode ergab ein ebenfalls als Hydrochlorid isoliertes Produkt mit einer Aktivität von 30.8,Ci/mmol. Die prozentuale Verteilung des Tritiums im [3H]Psicain auf die Benzoesäure-, auf die Pseudoecgonin- und auf die CH3O- Gruppierungen betrug 84.5:11.5:4.
