[2‐ 13 C]‐5‐Fluoropyrimidine‐2,4( 1 H, 3 H)‐dione ([2‐ 13 C]‐5‐fluorouracil or [2‐ 13 C]‐5‐FU) is a potential diagnostic agent for measuring 5‐FU‐induced toxicity in cancer patients. It was prepared and purified with isotopic and chemical purity of>99% on a multigram scale in a two‐step synthesis from [ 13 C]‐urea. Preparative separation of [2‐ 13 C]‐FU and [2‐ 13 C]‐uracil was carried out by automated medium pressure silica gel column chromatography. The method is applicable to a broader range of 5‐FU isotopic analogs derived from labeled uracil. Copyright © 2011 John Wiley & Sons, Ltd.
