β¦ Synopsis
Reaction of sodium [ 13 C]cyanide with excess benzyl chloride gave $75% utilization of the isotope. Subsequent nitration, isomer separation and hydrolysis of the nitrile gave the required carboxy-labelled 4-nitrophenylacetic acid.

## Abstract The precursor for the title compound was prepared in a threeβstep synthesis. The ^13^Cβlabel was incorporated in the first step employing 2β^13^Cβethyl acetate and the ^15^Nβlabel in the last step, using ^15^Nβsodium nitrite. Upon pyrolysis the precursor forms three fragments, one of th
