Abstract

Synthesis of [^3^H]FCE 22178, namely 5,6‐dihydro‐7‐(1H‐[G‐^3^H]imidazol‐1‐yl)‐naphthalene‐2‐carboxylic acid 5 was performed in three steps from 5,6,7,8‐tetrahydro‐8‐hydroxy‐7‐(1H‐imidazol‐1‐yl)‐naphtalene‐2‐carboxylic acid 2 by bromination, catalytic tritiation and final dehydration, in an overall radiochemical yield of 48%. The product was 97% radiochemically pure and had a specific radioactivity of 9.15 GBq/mmol.
