Abstract

Isoxazole derivatives, 3‐sulfanilamido‐5‐methylisoxazole (I) and 3,3‐dimethyl‐1‐(5‐methyl‐3‐isoxazolylcarbonyl)‐urea (II), have been labelled with carbon‐14. The carbon‐14 label was incorporated into the C‐5 of the isoxazole ring to give (I) and (II) in 22.3% and 33.0% radiochemical yield based on acetone‐^14^C, respectively.
