Embodiment 1

[0040]5-(2-(dimethylamino)ethylamino)-8H-phthalazino[1,2-b]quinazolin-8-one

[0041]

[0042] The synthetic method comprises the steps:

[0043] 1. Under electromagnetic stirring, add the compounds anthranilic acid and THF to the reaction vessel in sequence, place the flask in an ice-water bath, add triphosgene in batches under stirring, and move the flask to room temperature and stir for 10 hours after the addition is complete. After the reaction, excess solvent was removed by filtration, and the filter cake was washed with petroleum ether to obtain a white hydrazinolysis product.

[0044] 2. Under electromagnetic stirring, add the hydrazinolysis product and hydrazine hydrate obtained in the previous step into the reaction vessel in sequence, stir evenly, and then heat and reflux in an oil bath at 105°C under nitrogen protection for 3.5h (TLC monitors the reaction process, Developing agent: V PE :V EtOAc =2:1). After the reaction was finished, cool, precipitate solid, f...
