Abstract
A synthetic procedure for 2‐^14^C‐N‐nitrosohexamethyl‐eneimine 1‐aza‐l‐nitroso‐(2‐^14^C)‐cycloheptane is presented. The starting material was 1‐^14^ C‐cyclohexanone which underwent ring expansion, reduction, and finally nitrosation. The synthesis resulted in a product in good yield (68% overall), which is chemically and radiochemically pure.
