To 870 mg (3.26 mmol) of 2-chloro-4-isopropylamino-6-nitroquinazoline was added 3.81 g (66.64 mmol) of allylamine, followed by stirring at room temperature for 4 hours. To the reaction solution was added water, 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 895 mg (yield: 95.7%) of a free base compound of the title compound.
