Abstract
A convenient synthesis of [1‐^14^C]acetylcholine iodide in two steps is described. β‐Dimethylaminoethanol is acetylated with [1‐^14^C]acetic anhydride and the ester β‐dimethylaminoethyl [1‐^14^C]acetate quaternised with methyl iodide to afford [1‐^14^C]acetylcholine iodide in an overall material yield of 50–52% and radiochemical yield 18%.

## Abstract A convenient synthesis with analytical monitoring of ^14^C‐cotinine is reported. ^14^C‐Nicotine was converted into ^14^C‐dibromocotinine hydrobromide perbromide. Debromination, achieved by using Zn dust/acetic acid, resulted in high yields (71%) of ^14^C‐cotinine.
## Abstract A simple and convenient laboratory procedure is described by which hordenine (III), labelled at the carbon residing on the benzene ring, can be synthesized by decarboxylation of 3‐ [^14^C]‐tyrosine (1) and subsequent reductive methylation of the resulting tyramine (II).
