实验步骤: A solution of o-trifluoromethoxyaniline (1.77 g, 10 mmol) in cold, concentrated HCl (11.6 mL) was diazotized at -5° C. (internal temperature) with a solution of NaNO2 (0.69 g, 10 mmol) in water (11 mL). After 15-20 minutes the mixture was treated portionwise with a cold (0° C.) solution of tin (II)chloride dihydrate (4.5 g, 20 mmol) in concentrated HCl (4 mL). Stirring was continued for another 3 hours with the ice bath warming to room temperature after one hour. The suspension was recooled, basified with 50% NaOH (to pH 14) and extracted with ether. The extracts were washed with 1N NaOH, water and brine, dried (MgSO4) and acidified with an excess of ethereal HCl. Removal of the solvent in vacuo yielded the title compound as an off-white solid (2 g, 88%). It was used without further purification. was diazotized at -5° C. extracted with ether The extracts were washed with 1N NaOH, water and brine dried (MgSO4) Removal of the solvent in vacuo

实验步骤: 2-(Trifluoromethoxy)aniline (50 g, 0.282 mol) was dissolved in DME (1000 mL) and cooled to −5° C. Sodium hydride (12.3 g, 55%, 0.282 mol) was added in portions and the suspension was allowed to warm to room temperature. Ethyl chloroformate (23.5 mL, 0.245 mol) was added drop by drop and the mixture was stirred for 2 h at room temperature and for 1.5 h at reflux after addition was complete. Hydrolysis was with water (110 mL). The phases were separated and the water phase was extracted with ethyl acetate. The organic phases were washed with brine, pooled and dried with MgSO4. Evaporation of the solvent yielded 70.6 g of a brown oil, which was purified by chromatography on silica gel with hexane/ethyl acetate (6:1). This yielded the title compound, (44.2 g, 62%) as a beige yellow oil.
