Reaction of 3-Allyl-6-methyl-2-thiouracil with Bromine and Iodine

Abstract

3-Allyl-6-methyl-2-thiouracil reacts with iodine to form 2-iodomethyl-7-methyl-5-oxo-3,5-dihydro-2H-thiazolo-[3,2-a]pyrirmdinium iodide. The reaction with bromine leads to the formation of a mixture of 2-bromomethyl-7-methyl-5-oxo-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidinium and 6-bromo-2-bromomethyl-7-memyl-5-oxo-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidinium bromides.
