Abstract

A class of novel intermediates is described that have utility in processes for preparing uracil herbicides; wherein the novel intermediates are compounds of formula (A) which are cyclized with at least one cyclizing agent of formula (B) to provide a penultimate intermediate to, or a uracil herbicide, both of formula (I) where (X)n, Y, Z, R, R?1, R5, R7, and R8¿ are fully described herein. Preferred are those where Y and Z taken together are -N=C(R2)-NR3-, (X)¿n? is 4-fluoro-6-chloro; R is hydrogen and methyl; R?1 and R2¿ are trifluoromethyl, and R3 is hydrogen.
