実験手順
190 mg (0.579 mmol) of 5-bromomethyl-7-nitro-2,3-dimethoxyquinoxaline, 159 mg (1.2 eq.) of diethyl 2-aminophenylphosphonate and 0.2 ml (2 eq.) of diisopropylethylamine are stirred at reflux for 20 hours in 8 ml of acetonitrile. The reaction mixture is evaporated and the residue is extracted with water and ethyl acetate. The combined organic phases are dried using brine and magnesium sulfate and evaporated. The title compound is obtained as a yellow solid.
