Procedure

4.00 g (13.4 mmole) of N-(2,3-dichlorophenoxy)carbamic acid phenyl ester synthesized in Reference Example 1 was dissolved in 60 ml of ethyl acetate. 3.32 g (33.5 mmole) of cyclohexylamine was added thereto, and the mixture was reacted at 60° C. for 12 hours. The reaction mixture was cooled to room temperature, and after an addition of 100 ml of ethyl acetate, it was washed with a 3% sodium hydroxide aqueous solution and then with a saturated sodium chloride solution, and then dried over anhydrous magnesium sulfate. Ethyl acetate was distilled off under reduced pressure, and the residue was recrystallized from ethyl acetate-hexane, whereby 2.84 g of the desired product was obtained as light brown crystals (yield: 70%).
