Compound 16, 2-[2,4-dichloro-5-(1-methylethoxy)phenyl]-6-methyl-4-(2-propenyl)-1,2,4-triazine-3,5(2H,4H)-dione, was also prepared by the method of Example IV using 3-bromo-1-propene rather than iodomethane in Step D. Similarly, Compound 50, 2-[4-chloro-2-fluoro-5-(1-methylethoxy)phenyl]-4-(3-fluoropropyl)-1,2,4-triazine-3,5(2H,4H)-dione, was prepared by treating Compound 17 (Example II D) with 1-chloro-3-fluoropropane.
