    • There is provided a novel and high yield procedure for transforming acid salts of 14-alkanoyloxymorphinans and derivatives thereof into the corresponding N-alkyl-14-hydroxymorphinans wherein the alkyl moiety on the nitrogen contains the same number of carbon atoms as that previously in the 14-alkanoyl moiety. In the process of the present invention, the acid is neutralized to the free base, the alkanoyl moiety at the 14-oxy then spontaneously shifts to the nitrogen and is subsequently reduced to the corresponding alkyl moiety. O-dealkylation at C-3, where an alkoxy group is originally present, is carried out in the usual manner. There is also provided a readily produced and readily disassociated adduct of the corresponding 14-hydroxy-N-alkanoyl morphinan-6-alkylene ketal with benzene, tetrahydrofuran, and the like.
