Procedure

To a suspension of 0.14 g of 60% sodium hydride in 5 ml of tetrahydrofuran was dropwise added a solution of 1.0 g of ethyl 3-(2,2,2-trichloroethoxycarbonylamino)benzoate in 5 ml of tetrahydrofuran, and the resultant mixture was stirred at room temperature. Then, a solution of 0.45 g of dimethyl sulfate in 5 ml of tetrahydrofuran was dropwise added, and the resultant mixture was stirred at room temperature for 3 hours. After water was added to the mixture, the mixture was subjected to extraction with ethyl acetate, and an organic layer was washed twice with water and dried with anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (eluent; hexane:ethyl acetate=4:1) to obtain 0.84 g (yield 79%) of the title compound as an oily material.
