Following the procedure of Example 4, N-methylcarbonyl 2-chloro-3-(2,4-dichlorophenoxy)-6-nitroaniline is converted, by reaction with HCl, to 2-chloro-3-(2,4-dichlorophenoxy)-6-nitroaniline, which is then reacted with potassium hydroxide and sodium hypochlorite, again following Example 4 procedures, to yield the final product, 4-chloro-5-(2,4-dichlorophenoxy)benzo-2,1,3-oxadiazole N-oxide.
