Abstract

7,8‐Didehydro‐4,5‐epoxy‐3‐ethoxy‐17‐methyl(^3^H)‐, and βˆ’17‐methyl (^14^C)morphinan‐6‐ol were prepared by substituting the N‐methyl group with/^a^carbphenoxy group which was then either reduced with LiAl^3^H~4~ or removed to remethylate the N‐atom with ^14^CH~3~I.

## Abstract The preparation of [^3^H]Sch 727965 from unlabeled compound and tritiated water was base catalyzed. Diethyl [^13^C~3~]malonate was used to prepare [^13^C~3~]Sch 727965 in five steps in 21.8% overall yield. In a similar manner, [^14^C]Sch 727965 was prepared in five steps from diethyl [2
