This paper describes the synthesis of deuterium‐labeled pregabalin. The stable isotopic‐labeled compound was obtained in nine steps starting from the commercially available 4‐[^2^H~11~]methylvaleric acid as the stable‐labeled reagent. It is used as an internal standard for analysis and metabolic stu

✦ Synopsis
Abstract
Ethyl isocyanate, N‐methylacetamide, N‐methylacetamide‐d3, and N‐methylacetamide‐d6 were reduced with lithium aluminum deuteride and then nitrosated with sodium nitrite to yield, respectively, nitrosomethyl (‐__d__3) ethylamine, nitrosomethylethyl (α‐d2) amine, nitrosomethylethyl (‐__d__5) amine, and nitrosomethyl (‐__d__3) ethyl (__d__5) amine. The characterization of the compounds by mass spectrometry is described.

Several methods for the specific deuteration of cannabmoids are described. Deuteration of the phenolic ring was accomplished by treatment with BF, .Et10 followed by quenching with a solution of Na, CO, in Da 0 resulting in deuterium incorporation in both the 2 and 4 positions.
