Benzenamine, 3-ethynyl- → N-(3-ethynylphenyl)-7-nitroquinazolin-4-amine

Participants

Reaction Steps

A mixture of 4-chloro-7-nitroquinazoline (2.0 g, 9.54 mmol), isopropanol (30 mL), and 3-ethynylbenzenamine (1.2 g, 10.00 mmol) was refluxed for 5 h. The reaction mixture was cooled to room temperature and refrigerated. The solid was filtered, washed with cold isopropanol several times, and dried in vacuo to give 2.6 g (94%) of N-(3-ethynylphenyl)-7-nitroquinazolin-4-amine as a yellow solid.
