Abstract
3‐(1‐Hydroxy‐2‐piperidinoethyl)‐5‐phenylisoxazole citrate, 31252‐S (I) has been labelled with carbon‐14. The carbon‐14 label was incorporated into the C‐2 position of the side‐chain to give (II) and into the C‐4 position of the isoxazole ring of the molecule to give (III).
The carbon‐14 labelled products (II) and (III) were obtained in 27% and 6.4% ratiochemical yield based on methyl iodide‐^14^C, respectively.
