The synthesis of a series of five deuterium labeled phenethylamine derivatives, 4‐bromo‐2,5‐[2H6]‐dimethoxyphenethylamine (2C‐B), 4‐chloro‐2,5‐[2H6]‐dimethoxyphenethylamine (2C‐C), 2,5‐[2H6]‐dimethoxy‐4‐iodophenethylamine (2C‐I), 2,5‐[2H6]‐dimethoxy‐4‐ethylthiophenethylamine (2C‐T‐2) and 2,5‐[2H6]‐dimethoxy‐4‐n‐propylthiophenethylamine (2C‐T‐7) from 1,4‐[2H6]‐dimethoxybenzene is described. The isotopically labeled compounds are used as internal standards in gas chromatography‐mass spectrometry (GC‐MS) assays.
