To 150 mg (0.46 mmol) of 2-chloro-4-heptylamino-6-nitroquinazoline was added 1.14 g (20.00 mmol) of allylamine, followed by stirring at room temperature overnight. To the reaction solution was water added, 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 140 mg (yield: 88.6%) of a free compound base of the title compound.
