実験手順

A solution of 4-(phenylamino)-6-nitroquinazoline in ethanol/water and a polar solvent such as iso-propylalcohol is reacted at reflux temperature with hydrazine hydrate and Raney®Nickel. The reaction mixture is filtered, evaporated and purified by silica gel chromatography, to give the product, 4-(phenylamino)-6-aminoquinazoline.

後処理

  1. filtrationThe reaction mixture is filtered
  2. customevaporated
  3. custompurified by silica gel chromatography
