実験手順

A mixture of 2-chloro-5-methoxy-benzooxazole (1.52 g, 8.31 mmol) and a 40% solution of dimethylamine in water (15 mL) was refluxed for two hours before it was cooled to room temperature and partitioned between ethyl acetate and water. The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo to give the title compound as a black oil (1.14 g): MS: (+) m/z 397.19 (M+1)

後処理

  1. custompartitioned between ethyl acetate and water
  2. dry with materialThe organic layer was dried over anhydrous sodium sulfate
  3. concentrationconcentrated in vacuo
