A mixture of (E)-N′-(2-cyano-4-nitrophenyl)-N,N-dimethylformamidine (1.00 g, 4.58 mmol) and 3-aminophenylacetylene (0.64 g, 5.49 mmol) in HOAc (15 mL) was stirred at 100° C. for 3 h. The resulting mixture was cooled to room temperature. The precipitate was filtered out, washed with ether, and dried in vacuo to give 1.23 g (93%) of N-(3-ethynylphenyl)-6-nitroquinazolin-4-amine as a yellow solid.
