Abstract

Abstract1,8‐dihydroxy‐[10‐14C]9‐anthrone (anthralin) was synthesized in good yield starting from readily available 3‐methoxy‐2‐(2‐methoxybenzyl)‐benzoic acid (3).14C was introduced via carboxylation of the Grignard derived from 3‐bromo‐2(2‐methoxybenzyl) anisole. This, in turn, was obtained from (3) by a Curtius and Sandmeyer reaction sequence.
