To a solution of 4-(3-cyanophenyl)-1H-benzo[h]quinazolin-2-one (112 mg, 0.377 mmol) in DMF (2 mL) was added tri-n-butyltin azide (312 μL, 1.13 mmol), and stirred at 110° C. for 18 hours. After cooled to room temperature, the reaction mixture was poured into 1M sodium hydroxide, and washed with ethyl acetate. After aqueous layer was neutralized with 1M hydrochloric acid, the precipitated solid was collected by filtration, washed with methanol, and with water. The obtained crystal was dried to give the titled compound as a yellow crystal (70 mg, yield 55%).
