Reaction Steps
To a mixture of 6-nitro-2-(pyrazin-2-yl)quinazolin-4(3H)-one (1.00 g, 3.7 mmol) in POCl3 (10 mL) was added N,N-dimethylbenzenamine (0.1 mL). The resulting mixture was stirred at 120° C. for 2 h. After the reaction was completed, POCl3 was removed in vacuo, and the residue was co-evaporated with toluene twice to give a dark crude product, which was used for the next step without further purification.
