## Abstract A synthetic procedure for C‐14‐labeled N‐methyl‐N‐nitrosoaniline is presented. Separate labeling of the methyl and phenyl side chains was achieved by using C‐14‐labeled methyl iodide and aniline, respectively. The overall yield of the four reactions was 62% and the final products were s
