Abstract
The corresponding 5-bromo-6-alkoxydihydroorotic acid derivatives were obtained by reaction of orotic acid, its methyl ester, and amide with bromine in methanol and ethanol. The reaction of methyl and butyl orotates with methyl and ethyl hypobromites gives 5,5-dibromo-6-alkoxydihydroorotic acid esters. Isoorotic acid reacts with methyl hypobromite to give 5,5-dibromo-6-methoxydihydrouracil.
