Abstract

N‐Nitrosobis (2‐oxopropyl) amine (BOP), a potent and selective pancreatic carcinogen in the Syrian golden hamster was synthesized with a ^14^C label in the alpha carbon. Oxidation of 2‐hydroxypropyl‐2‐hydroxypropyl‐1‐^14^C‐amine followed by nitrosation with sodium nitrite and hydrochloric acid gave radiolabeled BOP in 60% yield.
