## Abstract The high yield, four‐step synthesis of catechol‐U‐^14^C from benzene‐U‐^14^C is described. Intermediates in the preparation include phenol‐U‐^14^C and o‐methoxyphenol‐U‐^14^C [guaiacol‐(phenyl‐U‐^14^C)].

✦ Synopsis
Abstract
Uracil‐6‐^14^C (7). prepared in high radiochemical yield by conventional methods. has been converted to 5‐fluororacil ‐6‐^14^C (9) in over 90% yield using trifluoromethylhypofluorite. The use of this recently introduced reagent eliminates the necessity of preparing 9 from fluorinated precursors.
