✦ Synopsis

Abstract

The title compound 1b was prepared by tritiolysis of 5‐(O‐bromophenyl)‐2‐dimethylamino‐2‐oxazolin‐4‐one, 2, with 10 Ci of tritium and diluted with unlabelled 1a. The mass spectrum of the 2′ ‐deutero derivative 1c, prepared similarly, showed that 92.9 % of labelled compound was D~l~ with only 3.1 % D~2~ and that > 95 % of the isotope was in the aromatic ring.
