実験手順

2,6-Dichloro-4'-methoxy-2'-methyl-benzophenone (0.75 g; 2.5 mmol) is added to nitric acid (10 ml; 65%). The mixture is stirred at 80° C. for 1hour. After addition of water the reaction product crystallises and is chromatographically purified (flash column filled with 30 g of silicagel, elution with toluene). White crystals (0.35 g; 41% y); mp. 156°-160° C.

後処理

  1. customcrystallises
  2. customis chromatographically purified
  3. addition(flash column filled with 30 g of silicagel, elution with toluene)
