Abstract

^14^C‐Labelled myosmine ([2′‐^14^C]‐3‐(1‐pyrrolin‐2‐yl)pyridine) was synthesized for autoradiography studies starting from [carboxyl‐^14^C]‐nicotinic acid by initial esterification of the latter in the presence of 1,1,1‐triethoxyethane. Without any purification the ethyl nicotinate formed was directly reacted with N‐vinyl‐2‐pyrrolidinone in the presence of sodium hydride, yielding ^14^C‐labelled myosmine. The product was purified by silica gel column chromatography. The radiochemical yield was 15% and the specific activity 55.2 mCi/mmol. Copyright © 2003 John Wiley & Sons, Ltd.

## Abstract A convenient procedure to synthesize 2–^14^C‐dinitroso‐hexahydropyrimidine (DNHP) is described. The synthesis begines with the condensation of ^14^C‐formaldehyde and propylenediamine‐1,3 in benzene with azeotropic removal of water. The resulting bases are isolated from the reaction mixt
