Embodiment 1
[0034] In the structural formula of the cyclomalonamide compound with anti-tumor activity, R 1 for CF 3 , R 2 is Br, prepared by the following steps (see figure 1 ):
[0035] 1) Preparation of 7-bromoquinazolin-2-amine (compound 2) from 2-fluoro-5-bromobenzaldehyde (compound 1)
[0036] Dissolve 10g (49.2mmol) of 2-fluoro-5-bromobenzaldehyde and 13.3g (74mmol) of guanidine carbonate in N,N-dimethylacetamide solution, reflux at 140°C for 5h, after the reaction, the reaction solution Cool to room temperature, add 120mL of water, a large amount of solids are precipitated, filter with suction, and the obtained filter cake is 7-bromoquinazolin-2-amine, about 5g, yield 60%;
[0037] 2) Preparation of 7-(4-aminophenyl)quinazoline-2 from 7-bromoquinazolin-2-amine (compound 2) and p-aminophenyl borate hydrochloride (compound 3) by Suzuki coupling reaction -amine (compound 4)
[0038] 2g (8.9mmol) 7-bromoquinazolin-2-amine, 1.54g (8.9mmol) p-aminophenyl borate hydrochloride, 2.8g ...
Embodiment 2
[0048] In the structural formula of the cyclomalonamide compound with anti-tumor activity, R 1 , R 2 for chlorine.
[0049] Step 1) to step 2) are the same as steps 1) to 2) of Example 1, that is, preparing 7-bromoquinazolin-2-amine (compound 2) from 2-fluoro-5-bromobenzaldehyde (compound 1) , and then prepared 7-(4-aminophenyl)quinazoline-2 by Suzuki coupling reaction from 7-bromoquinazolin-2-amine (compound 2) and p-aminophenyl borate hydrochloride (compound 3) - Amines (Compound 4).
[0050] 3) Preparation of 1-({3,4-dichloroanilineamino}carbonyl)cyclopropanecarboxylic acid by condensation reaction of 1,1-cyclopropanedicarboxylic acid (compound 5) and 3,4-dichloroaniline (compound 6) (compound 7)
[0051] Under nitrogen protection conditions, 12.9 mL of anhydrous triethylamine was added dropwise to 4 g (30.8 mmol) of 1,1-cyclopropanedicarboxylic acid in dichloromethane solution, stirred for 30 min under ice bath conditions, and then slowly added dropwise 2.3 mL SOCl 2...
