[0699] When the present compounds are used as the active ingredients of herbicides, the application amount, although it may vary with the weather conditions, formulation types, application times, application methods, soil conditions, crops to be protected, weeds to be controlled, and other factors, is usually in the range of 0.01 to 20,000 g, preferably 1 to 12,000 g, per hectare. In the case of emulsifiable concentrates, wettable powders, flowables, concentrated emulsions, water-dispersible granules, or other similar formulations, they are usually applied after diluted in their prescribed amounts with water (if necessary, containing an adjuvant such as a spreading agent) at a ratio of 10 to 1000 liters per hectare. In the case of granules or some types of flowables, they are usually applied as such without any dilution.
[0700] The adjuvant which can be used, if necessary, may include, in addition to the surfactants as described above, polyoxyethylene resin acids (esters), lignin sulfonates, abietates, dinaphthylmethanedisulfonates, crop oil concentrates, and vegetable oils such as soybean oil, corn oil, cottonseed oil, and sunflower oil.
[0701] The present compounds can also be used as the active ingredients of harvesting aids such as defoliants and desiccants for cotton (Gossipyum spp.), and desiccants for potato (Solanum tuberosum). In these cases, the present compounds are usually formulated in the same manner as the case where they are used as the active ingredients of herbicides, and used alone or in admixture with other harvesting aids for foliar treatment before the harvesting of crops.

[0892] 1H-NMR (CDCl3/300 MHz) &dgr; (ppm): 3.76 (bs, 2H), 5.78 (bs, 1H), 6.41 (d, 1H, J=8.3 Hz), 6.7-6.9 (m, 2H), 7.0-7.1 (m, 2H), 7.09 (d, 1H, J=10.2 Hz)
[0893] Second process:
[0894] Into a mixture of 4-chloro-2-fluoro-5-(2-hydroxyphenoxy)aniline [Intermediate Compound A3-4], methyl chloroformate and tetrahydrofuran is added dropwise N,N-dimethylaniline, and the mixture is stirred at room temperature. Dilute hydrochloric acid is added to the reaction solution, and this is extracted with ethyl acetate. The organic layer is washed with saturated saline, dried over anhydrous magnesium sulfate, and concentrated to obtain 2-(2-chloro-4-fluoro-5-methoxycarbonylaminophenoxy)phenol [Intermediate compound A9-4].
[0895] Third process:
[0896] 2-(2-chloro-4-fluoro-5-methoxycarbonylaminophenoxy)phenol [Intermediate compound A9-4] is dissolved in N,N-dimethylformamide, then, potassium carbonate is added, and the mixture is stirred for 1 hour at room temperature. Then, methyl bromoacetate is added at room temperature. The mixture is stirred at 60° C. for 2 hours, poured into water, extracted with ethyl acetate, and the organic layer is washed with dilute hydrochloric acid and water, dried over magnesium sulfate and concentrated to obtain methyl [2-(2-chloro-4-fluoro-5-methoxycarbonylaminophenoxy)phenoxy]acetate [Intermediate compound A9-22].
