Reaktionsschritte
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.
