Abstract
6-n-Propyl-2-thiouracil-6−14C was prepared from sodium butyrate-1−14C, with a radiochemical yield of 34%. Butyryl chloride-1−14C was prepared from butyric acid-1−14C and condensed with sodio ethylacetoacetate to yield ethyl β-oxohexanoate-β−14C. The β-keto ester was condensed with thiourea in sodium ethoxide to yield the 2 substituted thiouracil.
