The present invention relates to a method of mono-alkylating a piperidine nitrogen in a piperidine derivative with a deuterated lower-alkyl, which comprises protecting the piperidine nitrogen with an aralkyl protective group, lower-alkylating the piperidine nitrogen with a deuterated-lower-alkylating agent under neutral or basic condition, and then deprotecting the aralkyl protective group.
This disclosure relates to novel morphinan compounds and their derivatives, pharmaceutically acceptable salts, solvates, and hydrates thereof. This disclosure also provides compositions comprising a compound of this disclosure and the use of such compositions in methods of treating diseases and conditions that are beneficially treated by administering a σ
