✦ Synopsis

Abstract

The production of diethylstilbestrol monoglucuronide – (glucuronyl‐U‐^14^C) by incubation of uridine diphospho‐D‐ glucuronic acid‐U‐^14^C with diethylstilbestrol in the presence of guinea pig liver microsomes is described. The specific activity of the product was 9.1 mCi/mmole and the overall radiochemical yield was 13%, based on UDPGA – (glucuronyl‐U‐^14^C).

## Abstract A novel five‐step synthesis of 3,3′‐ dichlorobenzidine‐(phenyl‐U^14^C) dihydrochloride is described. The method consists of the preparation of benzidine‐(phenyl‐U‐^14^C) followed by acetylation, chlorination with N‐chlorosuccinimide (NCS), and hydrolysis. The specific activity of the pr
