## Abstract A selective and quantitative method was developed for a microscale preparation of 4‐thiouracil‐2‐^14^C by the direct thiation of uracil‐2‐^14^C. From pyridine, dioxane, and tetralin as the thiation solvents, the best yield was obtained in dioxane (96.6% of 4‐thiouracil‐2‐^14^C). The sim
