関与物質

反応手順

To a solution of 3.02 g (20 mmol) of methyl anthranilate in 30 ml of methylene chloride was added 2.22 g (22 mmol) of triethylamine. Into the mixture, a solution of 2.39 g (22 mmol) of methoxyacetyl chloride in 15 ml of methylene chloride was dropwise added under chilling with ice. The resulting mixture was then stirred for 1 hour. After adding ice, the stirred mixture was made alkaline by addition of 1 N aqueous sodium hydroxide and then extracted with chloroform. The organic portion was collected and washed sequentially with 3 N HCl, 6 N HCl, water and saturated aqueous sodium chloride. The washed chloroform portion was dried over anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure to obtain 3.6 g of the desired compound.
