The glitazone insulin sensitisers are an important class of pharmaceuticals for the treatment of Type 2 diabetes. Syntheses of [methyl-14C] and [3H]rosiglitazone maleate (BRL 49653-C), marketed by SmithKline Beecham Pharmaceuticals as Avandia® are described. [Methyl-14C]BRL 49653-C was prepared in 5 steps in 12.6% overall radiochemical yield from K[14C]CN. Catalytic reduction with tritium gas of a dibromo derivative gave [3H]rosiglitazone with a specific activity of 58Ci/mmol. Copyright © 2001 John Wiley & Sons, Ltd.
