Procedure
A mixture of 1.53 g (33.3 mmoles) of formic acid and 3.24 g (31.8 mmoles) of acetic anhydride was stirred at 60° C. for 2.5 hours, and 2.20 g (7.94 mmoles) of 1-t-butyl-3-(2,5-dichlorophenoxy)urea was added. The mixture was stirred at 60° C. for 5 hours. The reaction mixture was cooled to room temperature, and 100 ml of ethyl acetate was added The mixture was washed with a saturated aqueous solution of sodium chloride, 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 1.48 g of the desired compound as colorless crystals(yield 61 %).
