Procedure

100 mg (0.38 mmol) of 4-allylamino-2-chloro-6-nitroquinazoline was dissolved in 1.5 ml of acetonitrile, and 124 mg (0.76 mmol) of 2-propoxyethylamine hydrochloride and 196 mg (1.94 mmol) of triethylamine were added thereto, followed by stirring at 80° C. for 15 hours. Water was added to the reaction solution, followed by extraction with ethyl acetate, washing brine and drying over anhydrous sodium sulfate. After the solvent was distilled off, the residue was purified by a silica gel column to give 91 mg (72.3%) of the title compound.
