Abstract
Sodium 3-ethyl-7-isopropylazulene-1-sulfonate 1, which has been found to be a potent and chemically stable agent having anti-inflammatory and anti-ulcerous activity, was synthesized in 14C-labelled form by using potassium [14C]-cyanide. 14C-Labelled 1 with a specific activity of 9.02 mCi/mmol was prepared in eight steps in 21.9% overall chemical yield from 3-(t-butyldiphenylsilyloxy)propyl tosylate 10.
