Abstract: A new synthetic method of 5-bromo-3-sec-butyl-6-methyluracil(Bromacil) was described. Bromacil was synthesized using 2-bromobutane and urea as the starting materials in three steps including condensation, cyclization and bromination with total yield of 61%. The structure of Bromacil was characterized by

Key words: bromination , cyclization, condensation, Bromacil
