実験手順
A mixture of 250 mg (0.95 mmol) of 4-allylamino-2-chloro-6-nitroquinazoline and 864 mg (11.50 mmol) of 2-methoxyethylamine was stirred at room temperature for 2.5 hours. Water was added to the reaction mixture, followed by extraction with ethyl acetate, washing with brine and drying over anhydrous sodium sulfate. After the solvent was distilled off, the residue was purified by a silica gel column to give 214 mg (yield: 74.7%) of the title compound.
