Reaction Steps
In a mixed solvent of 20 ml of tetrahydrofuran and 1.9 ml of pyridine was dissolved 2.15 g (7.76 mmoles) of 3-(3,5-dichlorophenoxy)-1-isopropyl-1-methylurea, and then 10 ml of a tetrahydrofuran solution of 1.47 g (15.5 mmoles) of methyl chloroformate was added. The mixture was stirred at 25° C. for 2 hours. Water (100 ml) was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with a saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The ethyl acetate was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate/hexane) to give 1.14 g (yield 44 %) of the desired compound as the yellow crystals
