Substituted analogs of dextromethorphan (DM) are disclosed, which are shown to have substantial binding affinity at both NMDA and sigma-1 receptors, and which are degraded by human liver enzymes more slowly than dextromethorphan. The analogs are useful as alternatives to dextromethorphan, and can provide the same benefits without requiring co-administration of a cytochrome P-450 enzyme inhibitor.

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.
