Ein Kinderspiel! Die Titelreaktion mit Azomethiniminen 1 nutzt ein einfach durchzuführendes Verfahren, das auf der Kombination eines China-Alkaloid-Bromsalzes 3 mit KOH beruht. Das Verfahren ist verlässlich und allgemein anwendbar. Trifluormethylsubstituierte Amine werden durch zweistufiges Entschützen des Produkts (S)-2 zugänglich.
