Abstract
1‐Methyl‐2‐(2‐naphthyl)aziridine (1) and 1‐methyl–2‐(1,2,3,4‐tetrahydro‐2‐naphthyl)aziridine (II), psychotropic agents, were labelled by incorporating carbon‐14 into the carbon of the aziridine ring. Labelled products I and II were obtained in 32.4% and 14.4% radiochemical yield based on 2‐acetyl‐carbonyl‐^14^C‐naphthalene (III), respectively.
