Procedure:
5-(Benzyloxy)benzofuran (1.02 g, 4.55 mmol) obtained in Preparation Example 2-4, Step 2 was dissolved in a mixed solvent of ethanol (5 ml) and ethyl acetate (5 ml) and 5% palladium carbon (500 mg) was added, which was followed by hydrogenation at room temperature under normal pressure. After 2 hr, the reaction mixture was passed through celite and the filtrate was concentrated under reduced pressure. The residue was dissolved in dimethylformamide (20 ml) and methyl α-bromo-o-toluate (1.042 g, 4.55 mmol) and potassium carbonate (1.26 g, 9.10 mmol) were added. The mixture was heated at 100° C. for 1.25 hr and cooled to room temperature. The reaction mixture was diluted with water and ethyl acetate to separate the layers. The organic layer was washed with saturated aqueous sodium hydrogencarbonate solution and saturated brine, dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=9:1) to give methyl 2-[(5-benzofuranyloxy)methyl]benzoate (352 mg, 27%, white crystals) and methyl 2-[(2,3-dihydrobenzofuran-5-yloxy)methyl]benzoate (220 mg, 17%, pale-yellow oil).

Procedure:
A solution of 100 mg of sodium in 85 ml of n-butanol is placed in a flask filled with nitrogen and cooled to ca 5° C. At this temperature, 20 g (0.09 mol) of 3-ethyl-4,7-dimethyl-2,6-octadienoic acid ethyl ester are added. The mixture is then warmed to 60° C for 5 hours and to 100° C for 3 hours. For the working-up, the mixture is acidified with a few drops of glacial acetic acid and then the major part of the n-butanol is distilled off on a rotary evaporator. The residue is taken up in n-hexane, washed twice with sodium bicarbonate solution and three times with water, dried over sodium sulphate and evaporated. The crude product (19.3 g) is fractionally distilled. There are obtained 16.4 g (73%) of pure 3-ethyl-4,7-dimethyl-2,6-octadienoic acid n-butyl ester of boiling point 90°-92° C/0.04 mm Hg; nD20 = 1.4677.

Procedure:
The resulting 4-acetyl-3'-fluoro-4'-methoxybiphenyl (7.2 g) was dissolved in 300 ml of dioxane, and 360 ml of a solution of sodium hypobromite (prepared from 75 g of sodium hydroxide and 78 g of bromine) was added over about 40 minutes at 0° to 5° C., and the mixture was stirred at 30° to 35° C. for 2 hours. The excess of sodium hypobromite was decomposed with a saturated aqueous solution of sodium hydrogen sulfite, and 10% hydrochloric acid was added to adjust the pH of the solution to 3 to 4. The solution was left to stand at 10° C. for 20 hours to permit crystallization. The resulting crystals were filtered to give 7.2 g of 3'-fluoro-4'-methoxybiphenyl-4-carboxylic acid. Recrystallization from isopropyl alcohol gave 6.8 g of the desired product. Yield 94%.

Procedure:
Under a dry nitrogen atmosphere a stirred solution of 2.1 g (0.0062 mole) of N-[2,4-dichloro-5-(1-methylethoxy)anilino]trifluoroacetamidine in 130 mL of toluene was cooled in an ice bath. To this was added 5.2 mL (0.037 mole) of triethylamine followed by the dropwise addition of 45.6 mL of a 2.9% (0.013 mole) phosgene in toluene solution. After complete addition the mixture was heated quickly to 65° C. and stirred at that temperature for 45 minutes. The mixture was allowed to cool to room temperature and stir for approximately 18 hours. The mixture was diluted with 25 mL of water and stirred vigorously for a brief period. Sufficient concentrated hydrochloric acid was added to make the aqueous phase acidic (pH 2). The acidic aqueous phase and the organic phase were shaken briskly after which the organic phase was separated from the mixture and saved for further purification. The aqueous phase was extracted with methylene chloride and the extract evaporated to leave a yellow solid. This solid was dissolved in toluene and the resultant solution added to the saved organic phase from above. The combined organic phase was stirred at room temperature with decolorizing carbon and filtered through a celite pad. The filtrate was extracted with a 1N sodium hydroxide solution. This extract was washed with toluene and acidified with concentrated hydrochloric acid to pH 2. Sodium chloride was added to the acidic solution to the point of saturation. A precipitate formed upon cooling this solution and was collected by filtration. The filter cake was rinsed with several portions of ice cold water and dried under reduced pressure to yield 1.8 g of 1-[2,4-dichloro-5-(1-methylethoxy)phenyl]-3-trifluoromethyl-4,5-dihydro-1,2,4-triazol-5(1H)-one (mp 160°-161° C.), Compound 36.
