## Abstract Tritium and ^14^C‐labeled isomers of ethyl acetate are excellent substrates for competitive dual‐labeled radioactive isotopic measurements of β‐deuterium and β‐tritium isotope effects. Methods are given for preparation of the ethyl esters of acetic acid‐2‐^3^H, acetic acid‐2‐^14^C, and

Abstract
In support of a program to develop a treatment for depression, three isotopically labeled forms of the 5‐HT~1B~ antagonist AZ12320927 were synthesized. A tritium labeled version was synthesized for autoradiography using Ir‐catalyzed hydrogen–tritium exchange. A C‐14 labeled version was prepared for use in metabolism studies in four‐steps from [u‐^14^C]p‐nitrophenol. A stable isotope labeled version was synthesized for use as an internal standard for LC/MS/MS quantitation in two steps from chromenone 1. Copyright © 2008 John Wiley & Sons, Ltd.
