Embodiment 1
[0035] In the structural formula of the cyclosuccinamide compound with antitumor activity, R 1 for hydrogen, R 2 For F, prepared by the following steps (see figure 1 ):
[0036] 1) Preparation of 7-bromoquinazolin-4(3H)-one (compound 2) by cyclization reaction of 2-amino-4-bromobenzoic acid (compound 1) and formamide
[0037] Dissolve 5.0g (23.14mmol) of 2-amino-4-bromobenzoic acid in 80ml (2.01mmol) of formamide, and react for 1.45h under nitrogen protection at 150°C and a microwave power of 300W. After the reaction, the The reaction solution was added to ice water, extracted 3-4 times with ethyl acetate, and the extracted organic phase was washed with saturated sodium bicarbonate solution and saturated brine successively, then dried with anhydrous sodium sulfate, and then spin-dried to obtain a reddish-brown residue , the reddish-brown residue was separated by chromatography to obtain 1.89 g of reddish-brown solid 7-bromoquinazolin-4(3H)-one with a yield of 36.3%.

Embodiment 2
[0050] In the structural formula of the cyclosuccinamide compound with antitumor activity, R 1 , R 2 Both are trifluoromethyl.
[0051] Step 1) to step 3) are the same as step 1) to step 3) in Example 1, that is to prepare 7- Bromoquinazolin-4(3H)-one (compound 2), 7-bromoquinazolin-4(3H)-one (compound 2) and p-aminophenyl borate hydrochloride (compound 3) were obtained by Suzuki reaction 4((3H)-7-quinazolin-4-one)aniline (compound 4), 1,1 cyclobutyldicarboxylic acid (compound 5) and 3,5-ditrifluoromethylaniline (compound 6) in The acylation reaction under the condition of thionyl chloride gave 1-((3,5-bistrifluoromethylphenyl)carbamoyl)cyclobutanecarboxylic acid (compound 7).
[0052] 4) 4((3H)-7-quinazolin-4-one)aniline (compound 4) and 1-((3,5-bistrifluoromethylphenyl)carbamoyl)cyclobutyric acid (compound 7 ) generates the target compound (compound 8) under the condensation of HATU condensing agent, and the specific operation steps are:
[0053] Under ice-bath conditio...
Embodiment 3
[0060] In the structural formula of the cyclosuccinamide compound with antitumor activity, R 1 is chlorine, R 2 for CH 3 .
[0061] Step 1) to step 3) are the same as step 1) to step 3) in Example 1, that is to prepare 7- Bromoquinazolin-4(3H)-one (compound 2), 7-bromoquinazolin-4(3H)-one (compound 2) and p-aminophenyl borate hydrochloride (compound 3) were obtained by Suzuki reaction 4((3H)-7-quinazolin-4-one)aniline (compound 4), 1,1 cyclobutyldicarboxylic acid (compound 5) and 3-chloro-4-methylaniline (compound 6) in chlorine Acylation under sulfoxide conditions gave 1-((3-chloro-4-methylphenyl)carbamoyl)cyclobutanecarboxylic acid (compound 7).
[0062] 4) 4((3H)-7-quinazolin-4-one)aniline (compound 4) and 1-((3-chloro-4-methylphenyl)carbamoyl)cyclobutyric acid (compound 7) Generate the target compound (compound 8) under the condensation of HATU condensing agent, and the specific operation steps are:
[0063] Under ice-bath condition, 0.59g (2.49mmol) 4 ((3H)-7-quinaz...
