Reaction of 3-cyano-2-methylthio-4H-quinolizin-4-ones (I) with active methylene compounds afforded compounds (II) in which the methylthio group and active methylene were exchanged. Reduction of ethyl 2-amino-3-cyano-4-oxo-4H-quinolizine-1-carboxylates (V) with sodium borohydride was found to produce ethyl 2-amino-3-cyano-4-oxo-1, 6, 7, 8, 9, 10-hexahydro-4H-quinolizine-1-carboxylates (VII).
